This will be as close as I will be getting to a Paker Big Red.
I think these were produced in the early 80's but I am not 100% sure on the date but I do remember having then as advertising for my business when I opened up in 1983.
I was able to get a section that worked with the inner cap liner and all I had to do was drill out the black cap a bit for the nib.
It takes a converter as well as a Waterman long cart.
So now I have a retro looking work pen that did not set me back to much.
