RE: Spinners for Mosquito
$100.00?!!!
It looks like you could use any "deep" parabolic spinner, such as those for the P-51's...
Just measure the size on the engine cowl, that you want...
You could use any inexpensive plastic 6.00-9.00 black spinner.
At worst a second party spinner may not be as "deep" as the one pictured, but it may actually look better.
BTW: If you are scratching your plastic spinners with your electric starter, change the starter cone for someone else's, and keep them clean.
The ones that are provided with the starters tend to cut into the plastic (and aluminum!)....
I picked up a couple at my LHS, which were white in color and they do not even burnish the plastic. After many starts the plastic looks pristine, let alone how well it treats aluminum cones.
I picked up one bluish cone from Tower that was very gentle on the spinners, but it quickly fell apart. The white ones I picked up from my LHS have been fantastic and hold up well... but I do not know who manufactures them.
