These 20mm M3 Stuart tanks were part of a 20mm Rapid Fire Desert War game that was displayed at Reveille II.
They look very good, and the scenery was nice. Not sure of the make or if they were plastic kits or resin models.
Update: From the comments, they are the old Matchbox plastic kits of the M3 Stuart tanks.
The Nofila game from Monty’s Desert Battles was put on by friends of mine, Don & Alan. The Stuarts were the old matchbox plastic kit.
