Lifter Questions
 

Hi: I'm looking at a lifter with sn given as 22xxx

It is on the net at a gun shop. the person replying does not seem to know for sure what it is and he called it "Parker Arms". The one pic looks like a grade 0 or maybe grade 1 lifter.

Did any other gun makers produce Lifters?
Is there any Meriden Conn markings on barrel ribs or anywhere else?
Is there any fool proof markings that indicate the gun will be a Parker Bros. Meriden Conn made gun??

What is a reasonable price tag if the gun is good (shooter vs collector piece)

Thanks,
Jack ("itis" is telling me I don't have a Lifter)
