Since the PM is not working, I decided to post this here for all to see. It's a sheet containing all the tubing sizes for replacement of gun barrels in all scales. Aggieman asked for help in another post and this was the only way I thought I could reach him. Soooooooo, I hope you see this Aggieman. Anyone else that can use it is welcome to it.

Stay Safe.
