The last time I took on a challenging restoration was when I tried to repair the telescopic piston of my 146G. I received fantastic help and encouragement from you guys through the journey. So, I'm back with another challenge...
I bought this MB 432 (wartime) period stylographic pen for $75:
These are rare pens - the ones that don't work sell for between $150-250 and the ones that do work sell for over $450. I have been trying to get my hands on one for over a year.
This is what a good specimen looks like:
The pen I bought was cheap because the gold/steel wire feed is stuck in the nib pipe. See pic:
I wrote to every restorer in the US and in Europe that I have heard of - more than 10 of the best. I even sent it to FP nibs to check out and they sent it back. Professionals will not work on this nib because it's too risky and the parts are not available. I understand completely, and I appreciate their honesty and humility.
But, this means I will need to try and fix it myself. So, here begins the journey...
I tried to somehow drill out the wire feed stuck inside the steel pipe, but the opening/hollow in the pipe is so tiny that no drill can successfully take it out without damaging the pipe itself. One professional restorer tried and gave up. So, I figured that I will simply need to remove the pipe and wire unit and replace it with something new.
Step 1 - unscrew the nib unit's plastic housing from the section:
Step 2 - Use pliers to pull out the steel pipe. Twist and pull (twisting was most important):
Step 3 - Measure all dimensions of the steel pipe and wire feed inside it so that we know what the replacements should measure:
Step 4: Source replacements for:
a. Steel pipe
b. Wire feed
