If you have the luxury of time here, and you are sure you wish to sell those two 12 gauge Parkers, Dave's advice is "right spot on"--even though I don't normally buy guns from the various sites on the Internet, a good perusal of them all is an education-and I think you'll see the best fotos show All the details available.
I don't know Dave personally, but a few months ago he was looking for some firing pins, and as we both have a machinist background, it was a pleasure to correspond with someone that accurate. He also noticed the Dog's head buttplate on your Trojan (something I missed) which is NOT factory- they use a plain black plate normally with vertical 'hashed marked" lines, and no grip cap on their economy grade Parker-
Don't be discouraged- as someone said about "small details", they are most important to the serious collectors and shooters of "America's Finest Shotgun"
