Does anyone know if there was more than one hammer identified for use at Chatham Ontario during the late SQ era? I don't want to go down a rabbit hole researching this if the hammers have already been identified.
I note that the 24.5 mm CDS has two (that I have counted so far) different letter sizes.
Is this type of question too nit-picky for collectors?
I have checked:
