Brompton pump mount? I have recently acquired a Brompton, which came with this zefal pump, which doesn't clip onto the frame:



The rear frame on my Brompton doesn't appear to have the cage-like mounts that new models have. The mountings that it does have are shown below. Are these intended for a pump, and if so, is there a specific pump that attached so these?
You have a Mk2 Brompton which uses a slightly shorter pump. I think your pump might be a Mk2 also. Does it physically fit within the frame? (the handle goes towards the axle).

The bit you are missing is the adapter bolt for holding the Zefal pump. This goes into the seatpost-end pump bracket and slots into the hole on the nozzle end of your pump. You could maybe improvise something with parts from a hardware store.

You could also try to get hold of a Bluemels pump, which is what the mounts were originally designed for, although these are now incredibly rare.

Much more info about Brompton pumps can be found in this Facebook post.
