Canadian 19-Set Working Instructions

[David Dunlop]

The attached picture is of the above noted manual issued in Canada for the Wireless Set No. 19 Mk III. It is in the usual wartime 5.5" x 8.5" size format.
Was a similar format manual ever issued in Canada for the Wireless Set No. 19 Mk II? I do not recall ever running across one, or for that matter, any manual that might have been printed in the USA for the Mk II production they were involved in during the war.

The reason I am curious is that I own a Canadian issued, built by Philco USA, 19-Set Mk II and am now wondering what Working Instructions Manual for this particular version I should be looking for, for this set.

For Canadian and USA sets.

Thanks for posting that! I am definitely going to have to keep an eye open for one. Interesting that the publication code for it contains 'PC'. Probably Philco Corporation, as the Mk III version of the manual has 'RCA' in the code.

There is no production date at all on either the transceiver or PSU of my Mk II, so the best guess I had was late 1942 or sometime in 1943. I see your manual is dated 1 August 1942. Brilliant! Slowly we make progress.

Let the quest begin!

My Mk.II is dated 1942 but with no month. It has no Russian markings and is very close to first set made being serial C-127. The pictures in the Mk.II manual show a similar unlingual set. I agree that Russian/English Mk.II sets would date mid 1942 to mid 1943 when it was replaced by the Mk.III set.

here are a couple I have. The MK II is provisional. I wonder if this is the first release.

The MK I & MK II has no date but must be early.

Great time line developing here for these manuals. Be curious to see if by the time Bruce Parker's edition hit the presses, what, if any, references were made in it to the Mk I Set. Would not surprise me if the Mk I was rapidly being withdrawn from service. No mention at all of the Mk I by the time the RCA Mk III Canadian manuals came out.

Based on Bruce MacMillan's manuals, it would appear Philco (P.C.) may have been the prime, initial US maker of the 19-Set Mk II and was responsible for all subsequent publication of the Working Instructions. I think RCA ended up in that position this side of the border, regardless of who actually made the Mk III sets.
