I just found a large, HEAVY PENDLETON coat, almost like a coat over a coat with the EXACT label. I can’t find ANY pics on the internet. Can you tell me anything about this coat? Is it from the same era? The label reads PENDLETON OREGON. Unfortunately this site won’t let me send a piv. Thanks, Keith
Hi, My name is Keith & I have a Pendleton heavy coat that has the same label as your 1930’s Pendleton shirt. I was trying to get an idea of how old it was so I could have an idea of it’s worth. It looks like a Mackinaw but I can’t find ANYTHING by Pendleton that looks like this. I contacted Pendleton but they said they don’t keep records of past products! I read somewhere else on the web that they stopped making this particular label with PENDLETON OREGON in 1942. If you think you might could help or would like to see some pics let me know. Sincerely, Keith
