Well, if I may join the group: my frame number is WM20 58764; originally the engine had the same number, but the bottom end was beyond repair so I replaced it.
Not much hope to find anything valuable in the cards; she came in a container with scrap from an Egyptian army museum....
And there is not much original any more, but nevertheless I am curious
