Stanley No. 42 Ship Carpenter's Bevel Rare!

This is an old Ship Carpenter's Bevel, marked No. 42. I believe it to be Stanley as it matches the reference book's sizes and material. It also has the original owner's name and the date marked 1872 on both sides.
On condition, it has some problems, the longer brass bevel blade and the boxwood on one side have been damaged. The boxwood has a split on 5 1/2" marked and is bowed there slightly (shown in 2 pictures). The longer brass blade is a bit bent up in the same area, could be repaired, the shorter blade is in good shape. There is some peening work that has been done over the years to keep the bevel blades firm in their position, so that accounts for the marks on the brass end joints, also it may be possible that the end pins have been replaced, they are steel. There is some scratches and dings, but not too bad overall. The boxwood has a reddish patina and some darkened area. The scale and the No. 42 marks are on both sides. I should mention that while the boxwood on one side is warped a bit, the other side is quite straight.
This bevel was designed to transfer angles from the protractor to the work piece. This is the best one that I've seen to date of it's kind, as it is a rather thin and delicate tool. This type is quite rare, perhaps for this reason. Still a nice collector's tool overall!
