[Bender]

Hi All,

 No idea if it's a member selling this old machine https://www.ebay.co.uk/itm/256018609813 but it was in the 1985 Heinze Wolff and the 57 tricycles documentary https://player.bfi.org.uk/free/film/watch-heinze-wolff-and-the-57-tricycles-1986-online at 24m.45s in.

 Well worth a watch, and who knows this machine may have some history. I've contacted the seller with the above info. it's not mine

A several of (unsurprising) appearances of a very young Mike Burrows in that documentary .
Also, the presenter, Professor Heinz Wolff, was a visiting lecturer when I was studying for my degree about four years after that documentary was made.
