this is a very long shot, but who knows. someone might be an expert here.
I recently aquired the remains of a Beyer Peacock and co manchester donkey pump in full size, i.e actually being off a gorton foundry loco from the 1850s. its niceley made, and a bit of a wreck, too. needs some tlc. however the bottom half is missing completely, if it was ever there, and Id love some close up pics of any loco with an existing similar pump. the first colour pic is a swedish example, on "prins august" from 1856. the other pics are of my wreck. anyone who knows of an example in a museum, id like to get in touch with the curators about it!
anyway for interest anyway,
