I have been given a number taken from a crankshaft, purported to be a RR Merlin, recovered by trawler from North Sea  of Angus Scotland.

I will be able to view the corroded engine remains shortly, but meantime I have been given this sequence taken from the last crankshaft throw* ( *which end of crank wasn’t given).

000HAK825W0(orD)17309   The first digit( 0) is indistinct amongst corrosion, so could be spurious. 

Does this marking indicate anything to do with Engine Number and/or type/mark of engine ?

Thanks

Brian
