Other markings are not readable but could include the AoS number '52', the tank name and T-number, plus maybe some loading code:

The name of the tank should be one of these four, since No.20 was RHODERICK DHU T212645, see http://proxy.handle.net/10648/ac053d...8-003048976d84

Hello Michel,

As I saw you reference to a Sherman Crab named "ROB ROY", I attched a picture of "ROB ROY IV" taken during a demonstration in the Netherlands shortly after WW2:

What exactly would be the name / official designation for this cage-shaped thing carried by the lads on the first photo below,
used as "crib grillage" for basing Bailey Bridges,
and apparently pretty standard given the numbers used in the second photo (Monty's Bridge in Caen):

as often, in thinkdefence.co.uk:

https://www.thinkdefence.co.uk/2011/...ging-supports/

So these are "Christchurch Crib bridging supports" or simply "Christchurch Cribs"

More on this page (search for 'Christchurch'):
https://www.thinkdefence.co.uk/2011/...tion-bridging/

where we (or at least, I ) learn that its offical name is "Bridging Crib 20 ton"

While looking for info on British and Canadian Pontoons, I noticed IWM has quite a selection of pictures.....I don't know if these are recently added to the site, or if I just missed them before, but I am attaching a few.

I am specifically looking for measurements and/or scale plans of MkV and MkVI pontoons.....or any info on possible survivors. If anyone knows of any drawings, please let me know. Post-war nato pontoons seem to be a dime a dozen here, but I can't remember seeing any WW2 Commonwealth pontoons.

I think this is in Burma, saw a pic of a similar truck there.

Hanno, this one maybe? (with the other truck in the background?)

The first pictures seems to show a pontoon in use as a sled!

I am presuming these pontoons were plywood, which could be a reason you hardly see any surviving examples (?)

[Ed Storey]

Pontoons and Centre Sections were both the same size:

25 feet 9 inches by 2 feet 6 inches.

Surviving examples in Canada are very rare as the surplus pontoons were mostly all burned in the 1970s. The example on outdoor display in Petawawa is a post-War Extra Wide Bailey Bridge although the panels appear to be primarily wartime.

I managed to save one of the data plates off of the pontoons which were being burned.

[Alex van de Wetering]

Ed, I can see why you saved that data plate!

Thanks for your comment on a survivor in Petawawa. It looks rather nice and I agree that the Bailey section is the later type with the wider lower beams.
So far, I have just found one picture of the pontoons in Petawawa.

Is "2 feet 6 inches" the height from water level to the top of the pontoon? I am asking, because 2'6" seems a bit low for the full pontoon (?).

By the way, this time i am asking for a scale model.....I am not planning on making 1:1 repro pontoons (yet).

Alex

[Ed Storey]

I just checked my written source for those dimensions but I have not gone to a primary source to confirm.

Here are a few images of the CFB Petawawa Bailey Bridge. It was my Father who was behind saving the bridge back in the 1970s and the bay of bridging has been on outdoor display ever since. It is currently situated at 2 CER's Brennan Lake site. The pontoons have lost much of their originality as they have been rebuilt at least two times due to the deterioration from being outside for several decades. The pontoons were last reconstructed in 2018.

[Alex van de Wetering]

Ed,

Thanks for the additional pictures (and the article)...they are a great help. So, the pontoons have a special meaning to you! Was the "Storey" on the build plate of the other pontoon family as well?

I can imagine that the wood suffers a lot from being outdoor......so for any survivors that weren't burnt for fire wood.....

So far, the Petawawa ones are the only survivors I have managed to find on the web....even though I am sure there must be one or two more hiding somewhere.
Out here there is a Diamond T 975 in the Overloon museum, but sadly it's not fitted with a set or original pontoons.

I am trying to source which publication the attached drawings are from that David posted earlier in this thread, as I am hoping to get a larger scan of the diagrams?
Does anyone know the source of these diagrams?

I am working on a Crossley IGL8 and was about to apply the TSB body to it based upon this photo but, I think it is an early Albion BY1. Firstly, the front hubs are finned and notice the absence of a panel outboard the driver's seat as in the early BY1 half cab versions. Also, I see no documented evidence the IGL8's were TSB bodied. Now I'm back to doing it as a Derrick which is a safe bet and well documented. I have a Retriever to use for the TSB.

Cheers,

Hello Guys.

Looks like this thread has been stagnant for a long while
I keep refering to it but for some reason I can not expand David,s photos.

I am currently working on a range of WW2 British Bridging trucks and we are about to start on a Bailey Bridge model.

Hopefully this thread can start up again.

[Mike Cecil]

Don't forget to put the Bailey Bridge components transported by jeeps on your list.

Does anyone know the source of these diagrams?

I am still looking for some higher resolution scans of the drawings attached. Does anyone know where these came from?




And does anyone know if there ever was a manual/publication on the Folding boat and pontoon equipment as used on the Canadian Diamond T 975's.....apart from the diagram from the design records?

regards,
Alex

[Ed Storey]

These are the FBE manuals that I am aware of:

Military Engineering, Vol. III, Part II, Equipment, Bridges (excluding Bailey)
Pamphlet No. 2, Folding Boat Equipment, Mark II, 1936
Pamphlet No. 13, Folding Boat Equipment, Mark III, 1945

Parts List for Trailers 4-wheeled 35-cwt, Folding Boat, Pontoon Nos. 1 and 2 Mark I, 1938

Provisional Handbook for Folding Boat Equipment, Mark III, 1941

Royal Engineers Training Memorandum
No. 16 June 1945 Carriage of Folding Boats in 3-ton Lorries

Army Training Memorandum
No. 14 1934 Folding Boat Equipment

[Alex van de Wetering]

Ed, Thanks for taking the time to look into this.

I have purchased copies the first two pamphlets you mentioned; Pamphlet no. 2, dated 1939 and Pamphlet no. 13, dated 1945.
The former shows some diagrams of very early trucks FBE trucks, which are not the ones I am after, but nonetheless interesting to add to this thread.
The latter does show the trucks with the 4 pillars, but only as a picture, not the diagrams that David posted here years ago.

[Ed Storey]

Yeah, that is the problem when you try to track down unatributed photographs that have been posted to a forum.
