Nice saw, of those I have 08s and 07. I recently used the 07 to make some shavings for oyster mushrooms haha. Quick possibly stupid question... I'm currently doing up a 015, it has what I'd imagine is the original solid nose bar and on it is stamped 10 75 20. I was wondering is this the date or am I up the wrong tree? If it is the date that would mean they changed the stamp daily?
