Can you identify this pump for me?

The one on the bottom of pic obviously. Not sure where it came from.

 

The bottom one could be from Optimus, Primus or Radius.
How long is the tube itself?
I could check with the ones I have.

Regards Matti

 

Thanks Matti. More pics attached.

 

Hello Jean, it could be a pump for a paraffin pressure stove and those usually need to be soldered into the tank, I have several similar unused pumps.

 

Oh well, it will just have to join my unused pile too Jeff. Unless anyone wants it?
