Antique? Masonic jewel

Some time ago I found this silver Masonic jewel. Could anyone help me dating the piece, or give some more information on the maker, etc?
The right hallmark is unclear, but the left one shows a T joined with an F. (or in other words a T placed on an F), and with - what appears to be - a small capital H on top.
Any help will be greatly appreciated.
