Square Barrel Round

Probably 5 - 6 years ago I did a deal with 'Triking' that involved them having a couple of rear wheels and drive plates and amongst my parts from them were a pair of square finned 950cc barrels (inc pistons) that had been fairly radically machined down. Some years before I had bought, cheaply via Ebay,  a pair of damaged  le man 1000 cylinder heads and so the other day I decided get the cutting disc and file out and to do my best to match the latter to the former. The main restyling is done with just the broken fins to be repaired and a little more filing / tidying up.
