I talked to Tony Foster about my knife he says it's a mis stamped 6208 whittler said he had one with 3 blades stamped as a 65. That 6265 and 6165 were both large frame knives first production was prior to 1920 in Bradford. I didn't think the blade was changed. It's been indicated to me knife is worth somewhere in the neighborhood of a lot,  Good day and my regards.................
