Inconsistent front rail pin size.

Terry,

One or two millimeters????  That would be huge for a rail pin, no?  Did you 
mean one or two thousandths of an inch?

In my book, a variation of 5 thou in rail pins is too much.  Pull and 
replace with a set of pins that your underpaid laborer (myself in my case) 
has taken the trouble to measure with a micrometer.
