1880 lifter checking

[Bill Ericksen]

HI,

How many lines per inch is the checkering spacing on a 1880 10 ga. 3 frame lifter?
I believe I counted 14 is this correct?

Thank you

Bill E.

The grade will determine this. Not the gauge or frame size. And even from gun to gun in the same grade there will be variation. Typically 16 lines per inch is as course as one will find on any Parker. Original checkering Tools were hand made and may not be exactly a given line per inch measurement.
