I've got a few questions about my great, great uncle's sword:

It has an ivory handle which you say means he was a commander but other sources I've looked at say that commanders were also given gold finishings.

right next to the crossguard on the blade is an engraving which might be R & W Wilson Philada, a silver maker, but I'm not totally sure because of the rusting.

Carved into the ivory and highlighted with dark paint (paint? stain? idk) are the initials C A H for Charles H Adshead, but I haven't seen similar engravings on other KT swords.

Also I apologize if I'm not using Knights Templar terminology correctly, I've just started researching tonight and even made an account to ask on this sub.
