I would like to thank
@Redfin and
@Mastermind for helping with the 2100 project. It's been a year or so since I looked at those two saws and said I think I can make one outta them. Let me tell ya, looks can be deceiving. A 1100 form 1973 and a 2100 from 1983 and a 285 were all used to make it happen. Even so it's not something I would recommend doing, the differences were staggering. Was all worth it when after a few primes the piston went up and down on its own for the first time in 30+ years. She sure does sound sweet.
