Hi - I have 2 brand new never been used before metering pumps. One for the resin and one for the hardener the ratio of which is 2:1 respectively.
They have a screw fit attachment so they can be screwed to the resin/ hardener container.
They originally came with some MAS epoxy I bought but are surplus to requirements so anyone wanting to make an offer let me know by PM. To buy a set from a shop costs around 10.

I'm guessing but postage wouldn't be much ~2 (packing is free and I'll only charge the postage unlike most eBayers...) as they are pretty light.
