11 Set stuff

[kevin powles]

Chris/Gents, You don't happen to have any spare switch faces/knobs to perhaps help restore this 11 set to its former glory?.

This turned up from Santa for Christmas. All I need now is the #11 set to complete the carrier.
Why do IPhone turn pics upside down? Must be an Aust thing?

This looks a lot like the tripod in that RCHA picture. Who would have used one like this? The markings on the scope are:
7x50
Gun Sighting Telescope
PATT 6-376
Canada Kodak Limited
Serial No CAN 6002
I Googled it and the serial numbers go up in the 8000 range so they must have been quite common.

I think that's a standard tripod, as used for some of the survey instruments. Its official name will be "Stand, Instrument, No.(nn)", and it's most likely fitted with a 1/2" Whitworth screw for attaching the instrument (theodolite, level, telescope, map table, etc.). I'm looking for a No.16, which has an approximately 2" thread for attaching the "Instrument, Flash Spotting, Mk.III" - the enormous hole is so that you can drop a plumbline from the axis pin on the instrument in order to place it precisely over your surveyed-in point for the outpost.

The markings on the scope are:
7x50
Gun Sighting Telescope
PATT 6-376
Canada Kodak Limited
Serial No CAN 6002

That is/was an actual gunsight, though I'm not sure what it's off - possibly anti-aircraft, or might be Naval. Unfortunately it's been subjected to the depredations of the Mad Brass Polisher at some point in its life, then had a pillar & claw mount fitted for tripod use.

I found a video on the AWM site with these views of an 11 set in an 8 cwt. I'm not sure of the type of 8 cwt though.

Can you provide the actual links rather than just pics ?

Most likely your phone was made in Northern Hemisphere.

Why No 11 especially Ewan and not #19??

Gina, have only ever found reference to ws11 installation.
Antenna base in place.

That looks like a standard 19 set base to me Euan . Mike

Mike, the other one I have looks more like a ground mount.

Yes I have a couple of those, it is part of the golf bag kit . It is a ground base .

Does anyone actually have a pic of the LP carrier with a antenna base fitted. I have searched everywhere and never seem to find anything . The 11 set is apparently the correct set but what did they use for a base ? I did find this .

The one on the vehicle is Aerial Base No.10 Mk.2, which is quite late-on and continues in use until the Larkspur sets and the conversion to VHF.

The ground mount one is Aerial Base No.11, and fits on a metal spike.

The WS19 originally used Aerial Base No.8 for HF and Aerial Base No.9 for VHF.

Base No.8 had a "concave" profile to the ribber insulator and a truly appalling method of retaining the aerial rods: the brass socket was slotted like a collet and had a wire spring wound around it with the ends formed into looks so you could squeeze the loops to release the grip on the aerial rod. It was not a success, as flexing of the spring caused it to break after a while, and you got a _lot_ of flexing on a moving vehicle. It was replaced by Base No.10, though US manufactured sets were still being shipped with the No.8 when WW2 ended.

Base No.9 was for the 'B' set and took Aerial Rod 'G'. It required a dedicated mounting, and there were three basic types of a square base with upright pillar.

Base No9A was the Truck and Ground Station version, fitted to a spring clamp for easy attachment to a wooden post, vehicle hoop, etc.

Base No.9B does not exist - there's a variation of the 'B' set base with a flat bottom, rubber gasket, and clamp ring. This was post-WW2 Pye, used with civilian mobile radio and to use up surplus component stocks.

Base No.10 replaced base No.8 and has a convex rubber insulator and a mechanical clamp with a butterfly nut to securely hold the aerial rod.

Base No.10 Mk.2 was an improved version, the clamp was a single piece rather than two riveted together, and the convex rubber base went concave at the point it was bonded to the metal in order to improve the strength of the bond (The Mk.1 was prone to separate).
In addition, the clamp screw was threaded at both ends to allow an aerial feeder to be attached to the clamp - this allowed the set to be connected to the top of the insulator rather than being fed from underneath.

Base No.11 was the ground mount used with the WS22, R109, WS18 and WS19 in certain setups, etc.
