Anyone want to chime in on what they think a swivel gun like the one in the pictures might possibly be worth. The pictures are not of the exact unit but one that is almost identical all markings and measurements are the same. The bottom is marked NHSS and on top 1-0-9. No other visibly markings. about 36" long and a 1" bore. The swivel and handle are no longer with the gun.
I any help would be appreciated.
