Stradale Gearknob - Needs Work!

[ProtoTipo]

Thanks Chris. Any idea what wood the original was made from, and what the threaded insert was turned from? Does anyone have an original that we could borrow to get them bang on??

As John says, quite a dense grain.
The captive thread is steel, I'll check the thread on the stick I have. The original stick is quite substantial, hence the 20mm ID on the knob.

The colour of the wood changes a lot where the clear coating wears through (see photos of Beta S1 knob).
