Bought a Testors 1/35 M3 Lee at Michaels with a 50% off coupon. I think it cost about $12.
It took about 5 minutes to screw it together; yes, there's no gluing!
Eventually (maybe) I'll paint it up as a British Grant in "the desert" (unless the British used Lees as well as Grants). Yes, I'm sure there are differences, but I don't care.
The turreted gun (whatever it was) is bent, but I'll replace it with a bit of brass tube I have lying around. And there's a square hole in the rear plate, for a switch I think, that'll need filling in.
Now I just need some ultra cheap British 8th Army, 1/32 or 1/35, I'm not fussy!
