Not really...the price could vary substantially depending on the work that's needed to put it right...Some photographs of the barrel and a description of the current condition of the various parts would help...Interesting play on words...Early Brough....Ian
In 2019, locally in WA state, I had my old 1943 M20 barrel rebored, valve seats & valves resurfaced like new and head & barrel top skimmed = $200. New +0.60 Italian piston with 2 oil rings + wrist pin = $100, new rod top bushing = $12. Annealed and reused the copper head gasket. I didn't have to, but I also bought new head bolts on Ebay, as the old bolt heads were rather corroded and pitted. Works like a charm.
