Yes, I'd assumed it was a foundry serial number but there are various other, larger "cast in" numbers and letters all over the case. The gearbox cases have a similar foundry number stamped in them....
Sand casting fine detail (like small numbers) is difficult though, I think it would have been easier to have a man with a set of number punches at the end of the 1st inspection process, just after they broke open the moulds....
