Thanks for the info, then I can understand that it is possible that the pen is dialed (the date engraved on the barrel) after being manufactured, it seems that making these pens was only during 1936 ... 1938, this no doubt ( and I think it only in was 1936 and 1937), then I ask you, who sets the zero 0 on the barrel, maybe Parker? or perhaps someone who has bought the pen ?, Does pens were made of this model undated? - And finally do not understand this sentence, Sr, David, please clarify if I'd appreciate a lot, you say this "" Repair at least possible, as there is some evidence Parker date stamped parts at time of use. "" mean that you should not repair or restore, can be non-genuine? authentic Parker? sometimes taducción does not correspond to what you want to say, I pray you tell me this in other words to better understand, my English is not perfect and sometimes slang translates to errors in the automatic translator (my machine Help).
Best regards and thank you very much again
