SD,
In the above I told you I cannot post photos here from my phone.
The pictures I posted above are camera photographs, Old, but that is what they are.
The picture with three pistols was taken by my friend and agent back home in the UK.
Re signature appearing slightly more slanted;
Were you under the impression that gunmakers at this time engraved their own locks?
Locks were bought in, even by the very best, and came with the name stipulated.
Lock filers, finishers and engravers were all out-work or peddled scheme.
Engraving;
Q,
Did you expect that engraving will be the same if from the same house?
As an example, I had a quick look through the first few pages of W. Keith and David Back's book, "Griffin & Tow and William Bailes"
The first 20 Griffin fowling pieces I looked at were all engraved differently. Some have similarities, but not the same.
All the very best,
Richard.
Edited to add a Phone pic of the T-Guard finial.
I sent the pic to my wife so she could send it to my email!
No email on my phone.
