Chelpark Sumo - ink test.

This vintage Chelpark pen has been identified now- it is called Sumo, found a faint etching mark on the lower part of the cap. wonder if they had laser in those days 45 years back- unlikely, must be some simpler method! The etched model name is very difficult to photograph, particularly on a black plastic body. I had some doubt earlier that it a MOTI from Chelpark , but finally seen a photo from fountain pen revolution site- this is different. Then found the name. looking for some detailed history of Chelpark pens in the internet. Anyone having this knowledge please help.
 
The ink filling mechanism consists of a built-in piston plunger, operated by twisting the barrel-end finial by 3/4 turns to purge out the air and then twisting back to draw in the ink. Works perfectly air-tight. Tested several times, found to hold about 10 to12 drops of ink.
 
There is a ink view window at the section end of the barrel, clear acrylic or similar material, now dark brown in colour. Either this is the real colour or it is the effect of ik soaking over the years. Can not tell for sure. One would need to hold this window against a strong light to see the ink.
 
The pen is fitted with original Chelpark nib, a fine ornate nib marked iridium point nib. This medium point nib writes too smooth, I did not have to attempt any smoothing on the tip.
 
Balance and grip comfort of this pen is too good. Being a light plastic pen this is well suited forn regular fast writing for school / college- must have been a regular student pen for those days.
 
Other areas of the pen that is impressive are the fine lines and curves, just too correct everywhere. A fine proportionate build with a matching design clip. Too bad this fine pen is no more manufactured.
 
I had detailed about this pen earlier, for a recap , here is the link : http://soumitrapencollections.blogspot.in/2013/12/vintage-chelpark-pen-moti.html
