Go to any WalMart or sporting goods store in PA and they can issue a license. It is over the counter electronically.
Your license does need to be displayed. Pin it to your hat, your back, on your chest - doesn't matter - just display the license.
Interested in finding old State Smallbore records from the 40's, 50's. and early 60's. My grandfather was an active and evidently good competition shooter as he won several state matches. Just no online records I can find.
