Hi Chris,
Here are the pics of my 19 set with the complete control wiring for a Sherman tank. I was fortunate to pick up near mint Control boxes and the associated cables from an eBay seller in Nevada, the sets were perfect with the exception of the rubber which was, to be expected, very brittle. It's not the best photograph but gives a good impression of the cables required. I've also included two drawings which will be familiar to all, which indicate the cables as 12-point and 4-point. From these two diagrams you can picture the ridiculous number of cable clamps required but frankly this seems to be a bit overblown, I can't imagine that many being required given the relatively short distances the cables had to go. I have a number of Sherman tank interior shots which back up my hunch. These drawings are also helpful because they identify the need for single 12-point cable clamps similar to Clamps #11 and #14 on Page 160 of EMERS.
Looking forward to your comments and findings!
Regards, Patrick

PS. I recently picked up a mint U.S. Signal Corps Mk.II so will likely opt to incorporate this unit into my display, rather than the Mk.III pictured in my photograph. It would appear that these Mk.II sets were being installed in the 76mm Shermans used by the British, according to the YouTube video which started this thread, so I think I can feel comfortable using a US supplied set for my Canadian Sherman M4A4 project.

Hi Patrick,

Yes, the Lend-Lease sets were all Mark II from beginning to end, though the really late production used Eicor supply units and the sets were modified for the 12pt-6pt dogbone. (My "intended for Pershing" unit is one of those sets.)

Somewhere I have the M4 "installation kit list" and layout drawings, but I suspect the "kit list" will only go down as far as "Hardware set #n" rather than a useful list of clip types and all the nut and bolt sizes.

I need to sort through the banana crate mountain (still not unpacked, three years after the forced house move), and finally catalog what's in each box - and chuck out things I will never ever use again.

Best regards, and Stay Safe,

Chris.

This is the problem with kit being made in three countries, each of which has their own part numbering scheme!

I found the wallet containing the installation documents for M4 Medium Tank 76mm and it's American. That said, the Installation Kit Register does go down to nut and bolt level...

1 Clips, Cable Fixing, Sets No. 302 PC/USA59442 ZA/USA0442
15 Detail 1 ----------------------- PC/USA59425 ZA/USA0425
05 Detail 2 ----------------------- PC/USA59426 ZA/USA0426
15 Detail 3 ----------------------- PC/USA59427 ZA/USA0427

I also found 10 x ZA15154 and 8 x ZA15153 cable clips.

I can't find any cross-reference at present, but ZA15154 is for a single braided cable about 0.75 to 1-in diameter and ZA15153 is for about 0.5-in cables (so may be for the cable between the rotary base junction and J.D.3 or possibly the Leads, Aerial (A set to variometer or B set to aerial base), but it seems a bit small diameter for that purpose).

Somewhere I have some boxed American clips (one size only, which will most likely be "wrong" of course) which may give me a clue as to the numbering systems.

Best regards,
Chris.
