Ever see a letter before the serial number
 

Ever see a letter before the serial number on the trigger guard extension?
Example N107xxx

On graded guns.

Thanks Bob.. I did not know that..

Actually, isn't it "No.", the abbreviation for number in front of the S/N on the trigger guard?

I have had a couple of Vulcan grade guns with the"No" prefix. Both guns were made right around 1900.

yea , somebody wrote the word "no" on all my trigger guards to, I wish they would have fired that guy before he did to all old guns

Yup, it is the stylized No for number. The right vertical upstroke of the N bisects the "superscript" o.

My most recent Parker is B1217. Not sure what the B means. It is obviously a very early one

All my hammerless Parkers have 'No.' preceeding the sn on the tang. None of my hammer guns have it.

I've seen it on some later higher grade hammer guns.
