Been waiting for all these years an M3 or M3A1 APC with or without Cupola or the M2/M2A1 (a short version of the M3 with MG railing around the interior) will be great!
The British, Americans, French and other allied armies used it...oh yes, as well as the Germans (captured ones).
Brian (CS):
If you decide to produce this one, forget about the opening hood...I have problems with those huge hinges in your upcoming Sdkfz 251.
Andy (KC):
Take a stab on this. You already have the basic mould from the M21 and the M16 Quad.

My ESP tells me that you are already producing this one with a full riding squad. It will be a great add on with the British Firefly. The M3 Halftracks' were used as communication vehicles by the British Royal Tank Regiment, HQ Section.
...and maybe a plain old jeep with trailer in tow (and maybe for us who buys multiple sets, a removable driver and passengers so it can be used in various diorama situation).
