Im fairly certain I remember pictures and an article about that bike in either Bike Magazine or possibly Classic Bike in around 1982… made me giggle then and still does

That was good, really enjoyed it. The model is on display at Cosford apparently. Next time we go down with some scrapers I`ll look out for it

Personally, Id ditch the girl, and look for another who appreciates your lawn ornament.
Alternatively you could tell her shes lucky she isnt with me. I like SR-71s. And I have an Enfield Constellation in the front room.In bits

I can think of a couple.

and the Napier-Bentley:

Why not find out what the original spec was and do that to it?
If you are considering powder coating, its but a short step to a bit of nice shiny chrome on the engine

If the metal is at all suspect, blasting is a very good way to blow holes in it, especially if you have a “mate” who cleans waggon chassis etc. Dont do this.
I work in metal finishing, and if I was asked to clean something like this to bare metal, first off, Id ask why. You are going to loose most signs of age, any paint markings will disappear. If you still wanted it done, Id hot soak clean it to get rid of any grease,paint etc, then take the rust off with a cold inhibited hydochloric bath, then Id probably dip it in WD40

No probably not.
However, some people have their own aircraft and might like some handy scrapers than wont damage the metal. I probably could have written more concisely but it was a long night.
The scrapers are made of perspex with a ground edge.

And while I think on it was the book was written by Derek Robinson, who wrote some very entertaining wartime flying tales. Better than Biggles anyway
