Saving Old Seagulls

Hi All
I have a pair of 40 pluss-es (one with a recoil starter?), a silver centuy plus with a cracked block and a British Anzani super single (I think) for sale. The 40 pluss-es look like they should run, the other two are spares or repair I think. Anyone interested. I am in Bournemouth, Dorset.
Cheers,
Justin

I saw these on Gumtree but missed the bit about the cracked block
can you post up the engine numbers for the Seagulls please

The engine numbers for the 40 pluss-es are:-
FP1428BB3
FP939H0
Silver Century plus
WSPCL 2656CC6

Thank you Justin
