Jani:
I would be very appreciative if at your leisure you could take a few pics and email them to me. E.H. more than likely is for Ernst Heinrich (Daniel Carl)?? Tanner who was the youngest of Carl Daniel Tanner's sons and he was born in 1842 and expired in 1912. I've seen exact dates for all three boys but for now they've slipped out of my hands. So I would guess that Ernst Heinrich Tanner attained the rank of master circa 1866 and that's about the time that things fell apart in Hannover. So that would put the date of manufacture of your pinfire in the 1870s which makes sense. Also if it has similar engraving, then Carl Daniel Tanner passed the skill on to Ernst Heinrich (Daniel Carl) Tanner. Could Ernst Heinrich Tanner have been H. Scherping's engraver or was Scherping an engraver in his own right but only influenced by Carl Daniel Tanner? Or was L.(Lorenz???) Eckebrecht an engraver also and Scherping drew from the well of both engravers Carl Daniel Tanner and L. Eckebrecht?
Kind Regards,
Raimey
