I wonder why the trigger guard tang was left so plain. It could have rcv'd at least the double border and a few accents like the top tang got.
I'd guess that the Initials on the TG bow were done after the orig engraving had been completed. Has that laid over the top look instead of
orig being incorporated in the TG engraving.
Is the trigger checkered (stippled ?) Looks like it kind of,,

Awfully nice looking Ithaca.
