These must have been heavily used and abused , worn out , trashed as you don't see many. Then we have the 77 that's much harder to find. Can't find any records for production so far. I have 2963 and that's the highest I've seen so far. I know of around a dozen 77 saws or a tad more. Seen a lot more 73 saws but still not one you see everyday. One guy that lives on the west coast said 73's are easy to find. Then others say you never see them so it all depends on what part of the country your in.
