Looks like you have another windmill vane on eBay. The one before went to nearly $70... supply and demand! I'll have to see how this new one goes as I need one for my brother's but it also needs a fan (one blade is busted).
Edit:
I just noticed on your sale "this one fits my Empire #56 model, not sure if it also fits the taller B-36 or No. 36 model". Here is a photo of them back to back. For mine, the only difference is the older one has "Empire" on both sides of the vane/tailfin. Otherwise they are the same.
