MG- I made some enquiries with SRM recently (well 4 months ago) regarding A10 barrels,their website lists them, but the relevant page is obscured by a large "NOT IN PRODUCTION" sign.I spoke to one of the staff there as I like many, could also use a decent set .The chap at SRM explained that problems with porous castings are the issue, as he said "BSA had their own foundry and any rejected barrels went straight back in the melting pot to be re-cast", I assume from this that casting iron has a high rejection rate due to porosity, and thus small production runs would be too costly..... They have done it before though, (according to the SRM web page under "Special Products") "using the original BSA" moulds ?, so perhaps they will yet make some, we live in hope.....Bob
