Manville Manufacturing Single Shot

[manville singel shot]

ok this was passed to me, I am told it was my grandfathers gun, it is a single shot, 12 guage gun made by Manville manufacturing company, the gun works like a syringe , you place the end of it in your paml and using your middle and index fingers you pull the tigger back to fire the gun, the barrel about 5 inches long unscrews off the gun, im thinking its a 1 shot tear gas gun, anybody have any info or pics on this gun? worth? rare? its not for sale just want info ,
