PENCO 53 junior disassembly

[Jacurutu]

The penco 53 junior is the smaller version of the 53. It's a piston filler.

The section is screwed on the barrel wit a LEFT-HANDED thread (righty loosey, lefty tighty). The material is also prone to shrinking, so you'll have to apply dry heat abundantly both during disassembly and assembly (also lubricate the threads with silicon grease).  Note that the gold band between the barrel and section is normally part of the barrel, in my specimen it's broken. The piston head is made of casein (it has the characteristic smell) and looks quite brittle, but fits well and seems to be functional.

The feed is cilindrical and you'll have to gently push it from the rear. Alignment of the feed with the nib is made easy by a slot at the rear end of the feed. The nib has a fine tip, it's elastic, with moderate feedback. The clip is spring loaded. Overall it's a nice pen, but it was quite frustrating to service.
