It is HS30 00319 and non original matching numbers (has L26 in it, original number is L24 021841). Body is less than perfect for a 'restored' car, but it seems solid in the right places.
I'll let GK510 fill you in on the rest and possibly show photos also.
I'm actually not sure what to value it at, given what I've seen. Guess it depends on if someone wants an early car enough?
