Looking for some help on this saw, not mine, but the owner was thinking of installing a new plate and restoring the handle. I thought I'd get more information for him before he takes it apart and makes it a user. Have a look at the photos. The Barber & Genn stamp on the back is the earliest listed in Barley's book at 1790. But according to the book, medallions weren't used until around 1820's. In fact, the oldest medallion in the book looks VERY similar to that on this saw. St. George slaying the dragon with the exception that this one reads "Royal Improved". I'm wondering if the knowledgeable folks here have any opinions on age and modifications made to this saw. Could the medallion be original, or it could have been a very old replacement for a broken screw? Or maybe the mark on the plate was used later than we think? Would the saw be worth saving as is, or is this common enough that he shouldn't feel too terrible making a user out of it?
