Vintage Fisher Space Pen G1 Original Packaging

Description

This is a used Vintage Fisher Space Pen G1. Gold-grid. Sealed-pressurized ink cartridge U.S. patent No. 3,425,779. The pen is in intact, clean and both buttons function properly. **The ink cartridge does
"NOT"
write. May require a new cartridge. Original packaging and brochure are included.
This is from my father-in-laws estate and I don't believe it was used very much if ever. I don't know the year of manufacture. The brochure indicates it was printed 8 74.
I can't find any information on the internet. Not sure what the G1 indicates. It may be Generation 1 but I'm only guessing that.
**What you see is what you will receive.
**Again, the ink cartridge does not write!
**Space Pen is being sold ""As Pictured" "As-Is"".
Comes from a smoke/pet free environment.
While I try to describe items as thorough as possible, I may miss something so please review the pictures and ask any questions about the item that I haven’t addressed.
Thank You for Looking

I forgot to included the Black and Lite Cyan. They were opened but never installed. I added pictures of those cartridges.
