Today I found a parker vacumatic in emerald green pattern. It has some unusual things as follows.
1. cap has a clip like a blue diamond clip without a blue diamond. It had never been there. the cap has a
black jewel, and a band with //\\ like pattern.
2. barrel has imprints 'MADE IN CANADA', 'PARKER VACUMATIC' under the parker vac writing something like 'R.E.G.D.M.S'
and most unusually 'PAT NO. 31_982', .53.is written. The no is somewhat hazy, so I am not sure about the third digit.
the semiflex nib says 'PARKER U.S.A.' The pen is single jewelled junior size one.
So anybody knows about the patent marking on vacs? And what is the date of the pen? It does not seem to have the usual date code.
And is it worth the $35 I paid for it? It is in excellent condition. I willsay nearmint
Thank you.
