Stamps on Parker Single Trigger Blade.

[OH Osthaus]

well - I agree its the last of the serial number

but it looks like there is an overstamp of couple letters on a different angle

maybe a "P" and another then a period

did you tell the owner you would be really really careful taking it apart?

[Opening Day]

Dean it looks ok to me. If you want I'll take a closer look at my skeet guns but it looks good, give me a call or a pm if something really stands out to you Eric

[Autumn Daze]

There should be crossed P,s stamped on the trigger blade also Dean.
