Yes its Peter
They are made out of polyester resin.
There not refab gear knob but a new molded one.
The mold was taken off a almost new one and the process reporduces every detail right down to the crinckly leather/vynl finish of the original stock one.
As to price ! Ha ! Ive been making these for years and could never get any one to look at buying them or even looking at them for that matter.
In the end I gave away my stocks and sent them to people here on the forum at my own expense then basically gave up trying. No one was instersted when I told them they were exact repros made of polyester resin and couldnt tell the difference even looking at point blank.
I started out at $50 and went right down to $30 for the stock one. Couldnt sell one. Almost a year of development work off ond on to get the stock knob molding process right so it could be made all in the one go.
I never bothered to work out a price for the C/F one as that is a bugger to make. You gotta make two stock ones cut off the side panels on one and uses the center section on the other. Then profile down the center section C/F it, make the H pattern, then put about 5mm clear over the top. Sand and polish to the right profile and then attach the side panels. Oh and I can make the stock one in just about any colour.
