16613 picked up today

[gerard88t]

Hi All,
I just wanted to share a picture of my latest sub in my collection. Picked it up in a trade today and I hope I end up bonding with it))) It's from 1993 according to its S serial. I had to take out one link and it wears as a sub is expected. I did notice a tube was missing in the link I removed. Can these tubes be purchased reasonably from somewhere or do I need contact RSC? Thanks for looking :)
