Whats the millimeter size??? 0.5 0.7???

Not sure but I think it is 7mm. It takes a refill for a pen by Parker called a T-ball hotter.

Will this pen patina over time with use?

Yes, brass will change color over time, this is normal

Can this use Fisher Space Pen refills?

I am not sure about the length and size of Fisher Space Pen refills. The length of the refill used in this product is 9.8cm, the maximum diameter is 0.6cm, and the minimum diameter is 0.2cm. As long as this condition is met, it can be used
