A friend of mine has a brother who is selling his UNFIRED SS Colt MKIV. My buddy has been secretly holding on to it for me for a couple of months. I thought he sold it for his brother. Called me last night and said to send him $400.00 and it is mine to keep. Wanted to pay me back for putting him on the best deer stands when he comes out of Fl every year to deer hunt. Always gets a shot at a big one and he goes home with 4-5 deer. His brother will take $800.00 for it. I believe it's 84-85 year model which is about the time his brother said he bought it. SN 10882 Cane I'm sure you will now something about it. Series 80.
