This morning, I took the barrel and piston, plus rings, to DAMICO Engines Ltd, at Unit 18, Roudham Park Industrial Estate,, East Harling, Snetterton, Norfolk NR16 2SN. Website: http://www.damico-engines.co.uk/
DAMICO Engines have a very good reputation and are specialist in race-tuned engines etc, so should find the Bantam rebore a doddle! More of this later.
