RCAF Wireless/Communications Equipment

While I think of it, the second line of the RCAF Data Plate reads "SEC/REF. No.", which for this set happens to be: 10EU/5479.

Can anyone enlighten me as to what "SEC/REF. No." is and what it relates to? My current guess is that it might be a specific RCAF coding or identification system, and the 'REF." is probably short for "REFERENCE". The "SEC" baffles me.

SEC/REF is Section/Reference number. In this case it is 10EU/5479.

Section number 10EU refers to valve type radio equipment and Reference number 5479 is the individual stores number for the receiver.

I believe this numbering scheme was began by the RAF and there are some references on the net as to what each section number means. There are quite a few section numbers.

Thanks for that information. The word "section" actually came to mind while I was thinking about that data plate, but for some reason I ruled it out as "too easy" for a piece of military equipment. Silly me!

I finally located a photo of the back cover, complete with wall mounting brackets. Seems easy enough to replicate, with the exception of the two columns of louvers. The only place I can think of that used to do that sort of work was custom automotive body shops many years ago, but it also looks like the kind of thing any well equipped sheet metal shop should be able to do.

Anybody had this sort of work done?

I have run across a 17 March 1945 Technical Memorandum from the Director of Signals, Canadian Army advising of proper lubrication of the tuning gear set for the AR88LF. The above noted lubricant is identified in stock as the one to be used for this work.

Does any one have any other references to DND 640, know if this item is still in stock, or what lubricant may have evolved from it in today's world?

A chap in Holland recently sent me some photos of his RCA AR88 speaker. It is a version designed with an open back, no outlet hole on the lower right side for the speaker cable and oddly, no holes on the bottom for mounting the RCA Speaker data plate.

The frame of the speaker element inside, however, has this unusual paint stamp marking. Could this be a date stamp? The middle '44' would certainly be on the money for a valid production year, but how would one read the '3' and the '5'? March 5, or 3 May?

Just wondering if anyone can confirm this would be a date stamp and how it would be read.
