Hello everyone
I've been asked to give some data about the CV of the CH4 Shuttle Space Pen by Fisher Co. that's somehow based on the original design of the AG7 which was first used in space by astronauts on Apollo 7 in 1968
here are the questions
1- Was CH4 used in NASA space program? when?
2- When was the first line of production?
actually it's so important for us to find answers and we will be so thankful for any help
Best Regards
