Unusual CALDO cylinder head on eBay

[IanClayton]

Robin Read's firm had Dan Taylor produce Dante (Dan Tay---) heads and subsequently Jem Marsh folowed from the same source ( the Horeston Horrors) with his Speedex heads, wheels etc --maybe your finned brake drums ??--- \\ so think this from Dan's shed.

Does anyone outv there know the sourcing foundries for " Cambridge" and Montgomery's "Super Accessories" heads??
