Generally, it is engraved with PARKER. Some are engraved with the deformed letter P of Parker's trademark. Some are not engraved with the name of the series. For example, some Century series are engraved with Duofold and some Drow series are engraved with SONNET

< p>The other thing is that the gold content of the pen tip is 18K-750, which means that the pen tip is made of 18K (that is, 75%) gold alloy. As for what metal it is made of, this is too professional to answer.

Some will also indicate the place of origin, UK. USA or something, but I have only seen this kind of pen on antique pens. It seems that new pens nowadays are generally not marked with this mark.

Also, the size of the pen tip is marked, generally from thin to thick, it is XF F M B BB 3B, etc. Some Parkers I forgot how to mark the thickness with numbers. I only remember that No. 65 seems to be XF and No. 10 is B or 2B. I can’t remember clearly.

The others are special. For example, the Century series is engraved in Chinese red. Chinese character "福"
