I think that the guides are more of an issue than the chain itself. They tend to get quite brittle with age and heat. I know that a special tool exists to feed a new chain into the M119 by linking it to the old one, (thereby making it relatively easy to replace the chain), I don't think it is factory however. I think it was custom made and a few copies were made. Not much help, I know...

The folks on *********.com have a lot of 119 and 117 experience.
