Dear Sirs, We have now obtained four more castings of our wheel cylinder part number GB.4178. These castings have been cored down the centre and are again made in RR.50 alloy. Have you got the time to machine two of these pieces for us? We believe you still have the blueprint. Yours faithfully, | ||
