The uniforms used in those two photo-shoots are part of a sub-collection of wearable uniforms that I badged up in the early 1980s. For example original WWII BD Blouses were $14.00, Canadian Leather Jerkins were $35.00 and that Denison was $50.00. I bought a lot of the BD and separated some for the collection of unissued kit while others were badged up with repro insignia or very cheap starch-backs that could be bought in the UK for $2.00 a piece. That particular Denison has a faded out label. The webbing is a mix of Canadian and British with some of the pieces post-WWII dated, in this case they all have brass fitting. These uniforms were great for tromping around Europe at a time when WWII items were plentiful and cheap; thankfully I never wore anything out, a very good friend of mine destroyed a nice pair of WWII British Ammo boots by wading in the channel with them; and since I am now too old to accurately represent a WWII soldier I press-gang my son (who doesn't collect this type of junk) into wearing them when I need a suitable model.
Back in the 1970s and early 1980s finding out what any of this stuff was, how it was worn and where to find it was extremely challenging; for this trip to Normandy in 1984 I was using a Mk V Helmet, although once in the UK there was a good selection of wartime Mk IIIs for sale as the British Army had just released its stocks of stored helmets onto the surplus market.
The High-Top boots in the Legion shoot are the same ones I fabricated from a pair of Canadian Mk III Combat boots to wear to Normandy back in 1984, at the time I had access to an original pair in the CHofO Museum in Ottawa to use as reference.
I now have a couple of pairs of originals in size 8, so they are too small to wear as they would have been nice to use in the photo-shoot.
The exotic stuff is always hard to find, but 30 years ago it was not nearly as expensive or reproduced as they are now. I won't comment on the Airborne BD Trousers as they are one of the most faked items and they sell for vast sums of crazy money and to be frank, there appears to be several types manufactured, but I don't have any primary source documentation on them.
Some of my fabricated kit has been used for events in Ottawa, this one at Dow's Lake for the Liberation of the Netherlands event some 10 years ago (I am the photographer).
This is me in the Tank Suit.
As I mentioned before, I now use my son if I need a model.
This was me striking a 'war-like pose' in The Former Yugoslavia some 22 years ago.
