Having the saw plate, brass back, and other parts to make at least another dozen backsaws, I came across this open handle design that I plan to replicate.
Doing a search through Simon Bailey's book British Saws and Sawmakers from circa 1660, the maker of this saw could be BROOKES Brothers (1862) or William BROOKES (1841 - 1871).
The original photo will need to be resized to accomodate 3 handle sizes Small; Medium; and Large. Dovetail and Carcass Saws.
I have some sweet looking dark Tas.Tiger Myrtle & figured Queensland Maple as 2 species of timber for the handle wood.
