I got these today, two in one box (in the UK at least).
They are in the original bright red plastic which I recall from my youth, unfortunately, while they provide the basis for WW1 conversions, the 'Ole Bill' parts are NOT included in the box. I think the 'military' parts were printed on card, so I guess if someone has a set and can scan them there is a market for these items.
I recall that the Airfix Magazine of the period had a number of projects using these kits.
I wonder if anyone will produce resin conversions for these?
Hope this is some interest.
