Dave,
A few makers used crossed hammers with some variation of course as well as some adding a combination of both forms of maker marks. Ours is as well a combination of both types of registered trade marks. The trade mark in letter form is what we want to key in on imo. Match it and we more than likely found our maker as long as they used crossed hammers. I believe its the stylized letters JH, or possibly JFH. Tell me you see the F as well! lol
Looking at the last one its more likely to be a K
For sure its no F inbetween
JK is my best shot
