Filthy Rich $$$$$$$$$$ 3,819.99

This was most likely the outcome of a couple rich dudes battling it out to see who has the most money.  A 1936 Knucklehead air cleaner (which I guess they maybe just came factory with an air horn?) . . . so this thing was obviously kinda rare?
I feel great for lil_simsy !  The buyer will pay almost $20 bucks shipping.  You could fit this in a Flat Rate $7.80 Priority box and make another +$12.15 ?  Bonus !
I can relate with "What's $5,000.00 in our pockets, is like $5 bucks in other people's pockets."
