Franklin Mint has both a 1/48th Scale 51D Old Crow and 51B Old Crow. I'm not real impressed with their D model, but the B looks decent. Just saw one at a Hobby Store locally a couple weeks ago.The B Model which seems to have more accurate lines.http://cgi.ebay.com/Franklin-Mint-P-51B-Old-Crow-Bud-Anderson-Signature-/370388675497?cmd=ViewItem&pt=Diecast_Vehicles&hash=item563ce2aba9Quick check comes up with the D model on E-Bay. 45 bucks, buy it now. Not bad for price. The Armour Franklin Mint D model has some shape issues but I think it's the only game in town in 1/48th for Old Crowhttp://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140330740969One signed by Anderson. 195 bucks.http://www.diecastsupermart.com/store/p/3543-P-51D-Mustang-Old-Crow-Bud-Anderson-Signature-Edition-1-48-.html
