I am looking for more info on the Asian made pen which is shown below: it is a copy of the Parker 51 Vacumatic.
I am aware of the Hero 100 and 616, which are copies of the P51 Aerometric, but I never saw or read about an Asian copy of the P51 Vacumatic.
There are two Asian (Chinese?) characters imprinted on the cap lip (see picture 2 below). Can anybody read these characters? These characters are also reproduced on the nib, besides the designation "61° 12K" (located on the bottom of the nib where you would normally find the "RU-PL & date code" on a P51 nib).
The clip is identical to a P51 feather clip. The chrome cap has a design of groups of 4 parallel grooved lines. The clutch ring looks identical to that of the P51 but it actually consists of three separate steel rings.
The feed and breather tube look identical to that of the P51. Also the collector seems to be a good copy with the typical narrow and broad groove in the lateral direction although the top part of the collector has a slightly different design compared to the P51 original.
The dimension and thread of the hood are identical to the original P51 Vac hood, so the hood is fully interchangeable.
The blind cap is of the same length as that of the P51 Vac but it is has a slightly more rounded top and a wider opening with a different thread compared to the original (see last picture). So the blind cap is not interchangeable.
There is no date code on the pen barrel (or anywhere else).
The overall build quality of the pen is quite good although I did not remove the vacumatic filler yet so I have no info on the design of the vac filling unit. The blind cap threads on the filler however have a slightly different design compared to the original (see last picture).
Any info on this pen is much appreciated.
