When I bought my roller I felt like it was at the high end but didn't want to come home empty handed. The winters are too long and I will be wanting to work on it. (have a '68 Sears twingle to get running too). My frame and wheels seem solid but could have done with original fenders to make what I paid for it balance out some. ($650-See my pic under 'what year is my simplex') I have taken a few measurments between my '48 and '52 roller to notice that the radius of the frame where the tank fits into is different and the space between those pipes(at the choke plate) is 1/2" narrower then the '48 is.
