I have a small collection of these (only 8, the CAD infection is in the early stages!) that I am restoring and noticed that the chainbrake/clutch cover can be plastic or metal. Since I dont know the history on most of these saws I dont know if the covers are original to the year. Can anybody tell me what year the chainbrake/clutch cover changed from plastic to metal for these saws. All are built on the same crankcase so I would expect that the changeover must be fairly common.
If you buy a new chainbrake/clutch cover for one of these today, is it plastic or metal?
