Griff,
I've built a lot of the Tamiya 1/48 kits and I have never seen a Stuart in that series. Do you have a model number? I had to get a couple of Stuarts from Master Fighter in Europe. One is done up as a Honey, see below.
Also, to the best of my knowledge, Tamiya never made a Grant/Lee... still looking for a 1/48 supplier for those... any information appreciated. Thanks.
