heat lab engine set

The dynamo on that rig is made by the same folks who made the 220V unit for our Ruston & Hornsby, can't quite make out what the engine is though, looks like a varibale-compression Petter of some sort, or maybe something else?

Text says it is a Petter

these variable compression jobs out and out laboratory specials like the Ricardo we had at Aston, or adapted from production SE's?

Petter certainly did a version of the AV1 called a LAB1, I had two goes at getting a complete set out of BR Derby Research Centre before privatisation, but a back-door deal spoilt my correctly tendered offer, so I never saw the goings of that one. They also had an engine with a cracked head which also walked.

Might be worth an ask then if it is of interest, but as I said, I have always found TEE's prices rather beyond what I thought reasonable
