The 5 frames are pretty rare with any type of barrel.
I had a Laminated steel 34" gun for awhile. As you can see by the description below it had open chokes and was a nice sporting clays gun. This one is the only one listed in the book as a lifter grade 2. I sold it a few years ago and I think it is up to Traverse City on a fireplace mantle.

Parker Brothers, Grade 2 Hammer Lifter, 10 gauge, mfg 1879, 34” Laminated Steel bbls, IC/IC, Pistol (ball) grip, 3” chambers, Steel butt plate, splinter forearm, double trigger, barrels stamped 6^7, #3 frame, LOP 14 ½”, DAC 2 1/8”, DAH 3”, 10 lbs 8oz

Kurt: It sounds like a very interesting gun. Do you regret selling it. I wonder if someone on the forum has a 5 frame gun like the one i have and if they could post some pictures of it. Have a great day. Thomas

I realize it's a lot to ask but I would have liked to know how many 4 , 5 and 6 frame tens were made and of course barrel length as well as Grade would be nice to know .

Neither the Parker Story nor the records list the frame size as far as i know - so i think that is a never to be answered question - i am not sure where the number of five 5 frames originated

Yes I'm aware of that just wish they could have and I'm sure they would have if it were something available to them at the time .

He didn't actually say that he said "If i'm reading the parker story right on page 268 grade 1 top action hammer guns with lam barrels it states that only 5 34 inch guns were made. WOW. If that is true then i wonder how many are left. Thomas "

I have a 4 frame 10ga with 32in barrels that are marked 6lb 8oz. It is a grade 3 top leaver hammer gun with a skeleton butt plate. Carvel

That one kinda fits in the turn of the century or a bit earlier live pigeon guns category does it not ?

Yes, the Grade 3, #4 frame gun needs a PGCA letter. Parker made such guns for their contract shooters as well as the general hunting public.
