i have since managed to get some of these models and after measuring them i reckon they are 1/49th scale.
i even have some abrams in stock!

That's close enough to 1/48th for me

[King Tiger]

I decided to pick one up out of curiosity, its actually about as long and wide as my hobbyboss 1/48 KV-1, and almost as tall, that's just comparing on sprue though.

Hull Length: about 15.1cm
Width: about 7.5cm
Height to top of turret: about 5cm

Once you stick it on a 2mm MDF base most 28mm models come to the top of the main hull, the gun will need modifying though, the front half is very thin

I think its 1/54 scale

If it's a Challenger II, it should have a hull length (not including gun) of over 8m, which is a bit more than the KV-1 (6m? 7m?), but not massively so.

Close enough for fun with toys!
