Checkering recommendatioms

[B. Dudley]

In graded Parkers there is easily a 4 lpi swing, even within grades. It depends on gun to gun and also era the gun was made. I have seen original DH grade guns with checkering as course as 18 lpi and I have see GH guns as fine as 22 or even 24 lpi. And I have seen Bs that are courser than some Gs.

Of course when I talk about like spacing, I speak in modern day tool terms since many original guns made 100 years ago with handmade tools are not exactly a given spacing. All the time I am gauging various guns and finding that more often than not, the original spacing is somewhere in-between the common 2 line intervals seen today.

True enough. Fortunately, on graded Parkers, the smaller lpi’s will accommodate standard tools even though the spacing might not be exactly the same. For example, an original near 20 lpi or so pattern can generally be handled with a standard modern 20 lpi cutter. Not so with the larger lpi checkering patterns of the Trojan.
