Hello, All. Does anyone recognize this ? No mfg.'s markings, plunger feeds with the turn of the knob!! Thanks, lou

Hello Lou, Looks like an old suction gun to me. I used them for emptying master cylinders and such. Used like a giant hypodermic needle.

Hey Dan. Thanks for the info . The tip does look like a needle!!
-
I would agree with the others. It looks a lot like the vacuum pumps for player pianos, except that the end/tip is different.
-
Hey Guys. Thanks for the replies. I did a little digging, and all of the suction guns I looked at have a T-shaped handle for drawing the plunger back from the tip. The one that I posted uses a screw feed to advance/retract the the plunger. This seems extremely tedious for extracting fluids/liquids. Have you ever seen on one with this type of mechanism? Thanks, Lou

Looks kind of like an air pump for a pressure gas lantern, but the needle type tip probably eliminates that.
-
That reminds me of the little grease gun my father used to grease the roller tip on his chainsaw.
-
I think it is a grease "gun". For applying grease to fittings. Not all grease fittings are like zerk fittings, but they do use a ball and spring. The needle tip would push the ball open and grease would be applied by turning the threaded shaft. Older Brit bikes used this type of fitting and similar grease "guns" were supplied with tool kits.
Similar grease applicators use a needle to push aside a rubber seal and inject grease into a bearing.
Is the other part just a cover for the needle? Does it thread on?

Hello, Al. The cover threads on. Looking at it more closely, there is a pin attached inside the cover that inserts into the needle shaft when putting the cover back on. To keep the needle cleared of the grease?? Thanks, Lou
-
Maybe the the pin in the cover seals the needle so grease doesn't pump out if the knob is turned accidentally.
Its hard to find equipment with grease fittings anymore. But you must have some tool over there with a fitting. If you want to test it on one of my 50+ year old Brit bikes, let me know. But I suspect the needle is more for sliding under a seal lip. The Brit grease guns have a sort of blunt taper tip.
-
Hello, Al. Thanks!! And yes, the tip on this one is sharp, with a tapered angle! Regards, Lou

The sharp needle identifies this for me. It is actually a hypodermic syringe to inject saline into hams and other meat for food presevation. We had one on the farm. Heavy, nickel plated, right? My grandfather did his own butchering, salt was a major preservative for years. Another use for it was a bit shadier. At county fairs, livestock shows, it was important the animals looked to be in good health, excellent specimens. Before taken to the show ring, bulls, steers, would have air or water injected under the skin to plump them up, like they use botox on humans now.

Use celery juice as a natural tenderizer. Natural form of nitrates, learned it off of "Diners, Drive-Ins, and Dives".

Hey guys, Thanks for the replies, and the cooking tips!! . I don't think this is a food grade device!! Anything less viscous than grease, or, a heavyweight oil, would seep past the leather seal on the plunger. I'm guessing that a food grade device would be made from Stainless Steel, ( this one is brass with chrome plating ), and would have Neoprene Seals.
