Hi, I just won a McGregor Anti-Freeze jacket, the kind made especially famous by James Dean in Rebel Without a Cause. Mine is dark brown however, not red, which I think would have been vastly more expensive. The seller dates it to the 1950s, but what do you think? http://www.ebay.com/itm/vintage-McG...s_Clothing&hash=item4ab2cac467#ht_5600wt_1334 How long were these jackets in production, and how long did the company exist? Could my jacket have been made later than the '50s, or is the seller accurate? Thanks!
