That reminds me I have an original Instruction Book for Contract C8330 - Engine and Frame Nos. WB30 101 - WB30 150 NOT FOR SALE but I can photocopy it if of help and send it to you. Like Ian I have never seen a Workshop Manual for a WB30 but would imagine they did exist and perhaps a copy is still about somewhere. I would also think there should be Spares Lists somewhere.

I've got copies of spares lists...Also an original factory drawing dated 1940 with sectioned views of a WB30 engine (full size) showing all the part numbers..It also shows dates for some of the later modifications...Ian

Thanks Ian/ Keith
I would like a riders book in particular - associated with each later production bikes - hoping someone here has one looking for a new home - I had heard there were some on the jumble scene some years back
Shop manual I will refer to b31 data to get me through
I have a printed parts list & also an electronic version which is multiple pages not a single document - a friend is working on this for me to consolidate these into a single pdf document

Interestingly, I was contacted by a forum member whose contact has access to factory drawings, they are in fact later spec WB30 with 7” brake - like my project
I am hoping he can work with his contact to obtain copies or scans of these - I have seen photos of them & they look very interesting & informative
Still hoping !🙏
