Jack,
That is not the Bluemels wheel I was expecting to see. My knowledge of Slough car trim is limited but that is almost certainly original as it looks the same as those on the Light 15s I owned in the distant past.
If you still want recommendations for a restorer, I refer you back to the Google search suggested in my earlier reply … it really does throw up a great deal of useful contacts and info.
