Hello,
I'm trying to resurrect an old HP 7475A, and I need a couple of parts:
1) the 6 pen carousel
2) the black plastic cap that goes on the left end (nearest the
carousel) of the rod that rotates in order to raise and lower the pen.
The pin that stick out of the end of the cap has broken off. I was going
to try to rebuild it with a short length of brass or plastic rod, but if
there's a spare out there, it would save me a lot of trouble.
Thanks in advance,
Stan Perkins
