"David" high-velocity anti-tank gun

[rob love]

Looking at the thread on BOCN that you linked to, I see there still exists an original round for this gun. I am not sure that we even have a round for it.

Could you imagine trying to identify something like that in the days before the internet?

Here is a photograph of "David" when it when it was still parked beside the parade square at CFB Winnipeg in 1997. I wonder what happened to the brass plaque that was on the gun shield?

No idea about the plaque.....if you look at the photos of the gun on the link I gave, there is one with a plaque of some form sitting loose on the breech ring. That photo was taken here in Shilo before I worked on the gun, so if that was the plaque you were talking about, then it appears to have found it's way loose.

[Ed Storey]

Yup that looks like it. I was hoping the plaque would be wartime with some unique information on it - oh well. Good to hear that Shilo has the gun and that it is not sitting in a scrap yard.

Any idea where the Pak 38 went that was sitting with "David" on the same parade square?

The PAK38 is still at 2VP.

There was a carrier there as well. The carrier had been assembled out of two, and was a bastardized mix of mk1 armour on a mk2 hull. They tried (unsuccessfully) to get it running for the anniversary that year. Later, a funding arrangement was made and it came to the museum for overhaul. I was able to get the engine running in short order, but out-door storage, a lot of wear, along with some 30 years of patchwork maintenance had really taken a toll on it. It was stripped just about to the bare hull and is now finally looking like something. It shoudl finally move under it's own power this week, once the steering box is back together and the linkages are adjusted. I think it will be one of the best carriers I have restored to date, although there are still signs on the lower that it was a mk2. Alas, that would be another thread.

There are some paper data files available on the dimensions of 20+mm calibre cartridge cases, the best known being one by Bob Hawkinson in the USA. Even that doesn't include this round though - too rare. So yes, I have to admit that the internet is marvellously useful to those of us with obscure hobbies!

Do your sources say anything about the muzzle velocity achieved with different weights and types of projectile?

[rob love]

I have nothing on them. I guess Doug Knight would be the guy to get a hold of. I am guessing he got his information from Archives Canada.

Not sure if we have any information in the museum's library. It's a different building than the one I work in, so I don't have much to do with that stuff.

Perhaps if somebody has Doug's booklet on the 2 pounder in Cdn service, they could relate what information is in there.

Gents,

If you are interested in an in-depth read of war-time documents pertaining to this gun see this link:

http://heritage.canadiana.ca/view/oo...2/1613?r=0&s=1

There are 3 files pertaining to it's development and trials:

55/2100/P2 - Proj No 2 - 2 pr David H.V. Gun - starts at image 1613 (above link) and ends image 1896.

55/2100/P2/2 starts at image 1898 and ends at 2144.

55/2100/P2/3 starts at image 2149 and ends at 2294.

The documents in these files are placed in reverse chronological order so the reader may wish to start at image 1896, work backwards to 1613, skip to 2144, work backwards to 1898 etc.

Happy reading!

Colin

Thanks, that one has arrived, along with Roger Lucy's book Secret Weapons of the Canadian Army (which has rather more info).
