Hi Wal, Mine's 0734 and there won't be many left between our numbers now.
what's the history of the engine ? is it the correct number with a newer camcover or has it had a transplant?
I see all the ancillaries are period for 0898 other than that. V nice indeed.
the earlier numbers , mine included , originally had a dark red straight grained dash( mahogany) which i've replaced with burr walnut as per yours, but i have the original still. I think yours may have had the burr walnut from the factory
