Went and looked at some tractors a lady is wanting to sell. In the trio is a 1948 Gibson model F or so it says on the placard they had on it. The only reason I went to look at em was to see what she had and maybe give a ballpark value on what she had. The problem she’s gonna have is they bought em when the market was appreciated and that’s what she thinks she’s gonna get. All the research I did on a Gibson model F indicated to me there never was such a thing. From all the photos I looked at it bore the closest resemblance to a model D with the 1 cyl. Wisconsin and joystick steering. Question is, did Gibson ever make a model F and if they did how rare would it be? Her last statement was, I’ll get what I want or they’ll sit. I think they might sit. Thanks for any input. DP
