On the Birmingham it is actually 2 lines that says
(top) T.DAVIES - (bottom) Birmingham and stamped on either side, 18----98;
On the Hart, what ever was there originally was lost years ago so we made the new 'Coin' to mark the Bass and fill the empty hole.
On the Dodd (Crown?), the first Bass shown, I have no idea what that says in the upper Back. The two diamond shaped patches in the neck button were a from repair done ages ago.
Also, on my Gilkes is has the location as well as the name stamped by the bottom Block on the Ribs;
When stamped, the names are usually shown but on occasion the place might be under it but never without the name unless it's worn away or missing from a repair.
