Parker 51 sac protector

[rwoolner]

Good afternoon-

 

Snow day here in New Hampshire- I have been catching up on grading and planning, but am taking a break to ask a few questions-

 

I have a "parts collection" parker 51 that I am working on.

 

First, the new breather tube- has a small hole in it- that end goes into the feed, correct?  But the tube does not go far enough in to... align that little hole with the hole in the feed tube.  Am I correct in understanding this?  That IS how I have assembled it, and it seems to work... the pen pulls ink into the sac, and it write well... 

 

Second-  are parker 21 sac protectors interchangeable with Parker 51?  Full size or demi size?  As of now, this "parts collection" 51 does not have a sac protector on it.  But it still writes, of course.

 

Sincerely,

Correct, the new little hole end of the breather tube goes into the feed.  The hole should end up about 3/8" above the end of the feed.  I turn the hole 90 degrees away from the nib slit, I choose right or left depending on the state color to keep peace.

 

The sac protectors are different. Running el fresco shouldn't be an issue until the correct part is located.  While I've never seen one advertised for sale, it fits into that parts category I term "mostly postage".

Good evening-Thanks for the information- regarding the breather tube, that's pretty much what I figured, but I didn't twist the hole right nor left.  I hadn't considered political leanings- I was more concerned about the coriolis effect.  EIther way, the pen writes nicely as is.  

 

And yes, without the sac protector, it writes just fine.  I will keep watching for the correct part- BUT... there seem to be different sized-threaded sac protectors, as the extra one that I DO have... is too large diameter, and will not work. I suppose I could pad it out a bit, and glue it...

It seems you have a 1948-1949 Demi size 51. The Demi threaded sac protector is smaller than the one on the standard size.
