xausa,
I have been doing some research since you pointed out your belief as to the sight staffs maker. I was wondering if you have any pics of PH sights that look the same as my staff? I haven't been able to find any.
I did find a similar shaft shown in the Old Gunsight book, I believe this is a staff made by King Gunsight company. At least it contains 2 pics that are very close.
If any of the sight collectors here can provide any input or pics it would be appreciated
