Yesterday, I was looking at one of my 51 vac fillers and replacing the whole filler(an all metal one, which works better than the standard one). When I came across the stamping of "Parker "51" Made in USA" Instead of what it should be, it reads
PAPARker 551
MaMade inin USUSA With overlapping stamps.
Is this common, and would this affect the value of the pen.
BTW its a 1946 first quarter production, jewled cap
