Parker 10ga. info. needed please

[DaveSmith]

Hello all, i am new to the world of parker having just received my Grandad's old parker. i am hoping someone can give me a little info. about it.

using this site to locate the correct info. this is what i found on the gun.

sn: 1213xx made in 1878 i think.

barrel weight: a big 5 and small 4 stamped on the table.

frame size: 3, which i think is a 10ga. a 12ga. shell will fit but its loose.

barrel steel: it says "twist"

grade: "P" yes, P i looked with a 10x loop and its a "P". not a PV or PH or any other combo.

now for the bad news, it is in very bad shape. it has been stored out side in a shed for the last 40+ years. if i had known it was there i would have got it decades ago. guess i should have asked grandma about paps guns sooner.

thanks for the help. Dave
