steel tubing & connectors to make a workbench (or other) (Cannon Court CB4)

Offered: a collection of 25mm steel tubing and connectors that I used to make a workbench,. (You could use it to make up something else.) You knock a connector into the ends of one tube, and push the other tubes onto the connector -- no screws or anything else. I bought the pieces from MacKay's in East Road in Cambridge; they still sell them , so extras are easily available.

Attached is a sketch of the workbench; all dimensions in mm. It's now dismantled so dimensions are only approx. Also attached are photos of the connectors so you can see what sort they are.

(Offer is tubes and connectors only; there's no board for the top of the bench.)

I'm away today so won't reply to messages until Monday.
