lol, o no need to be ashamed, none of us are experts in everything. I am just a big fan of the 251, one of my long term projects is to build one of every variant in every model, thats 63. So far i have i think 24, all Ausf C and D's. And i have been waiting 2 years since Dragon announced it was going to release an Ausf A So when i saw Ausf A my eyes light up. O well, back to waiting for dragon to pull the fingure out.
