    can anyone determine what kind of pump it is?!

    I got a good old hand pump from a friend and it seems durable and well made, it has no hose, but unfortunately I have no idea if it's hoseless or not, I couldn't find a hose on the internet that seems to match it. I've tried it on my bike which has a Dunlop valve and it was a bit loose but with some effort i managed to inflate the Dunlop valve tire, the pump was powerful but the non fitting valve was a problem.
    I compared it to some similar ball inflating pumps but it seemed different.

    I like the pump and I would like to keep it. so, I would be grateful if you guys helped me determine what type of pump it is. and which kind of hose or adapter I should use, since it doesn't match Dunlop or Schrader. could it be Presta? I'm not sure, I don't have a Presta valve. but the screw thread on the valve makes it clear that something should be attached to it, likely a hose or maybe an adapter.

    I've attached a pic of the pump and its socket with some descriptions.

    Thanks in advance

    Never seen one like that. I presume the 12mm male threaded nipple is meant to attach to a hose that has on its other end a piece that threads onto a Presta or Shraeder valve stem. The 10mm hex socket is used (with a 10mm hex wrench) to screw the nipple into (or out of) the pump body. Presumably...If it is a bicycle pump, it looks well made and rare...maybe even a prototype. Nice find!

    From the looks of it. I suspect that the internal socket is there only to attach the fitting to the pump body. The external threads probably rake a cap which holds a rubber washer under it, and the hole size (tightness on a PV or Dunlop valve) can be adjusted by tightening the cap.

    Thank you guys for all the answers, I just figured out that it's a normal old type frame pump and that it needs only a nut to be mounted on the threaded nipple. Unfortunately I couldn't find any on the internet. It would be great if you guys know where I can find such a small spare part. I've tried a plastic one from a relatively new frame pump but it didn't fit, the nut was a bit smaller, I just wanted to try find the missing part, otherwise I'll have to use it as it is or spend some money on a high quality pump.
