Try actually reading and understanding the text before calling somebody out on something. I'll put their text in quotation marks as copied & pasted from the auction ad.
"THIS IS A VINTAGE NEPTUNE 1.7HP MIGHTY MITE MODEL #WC1 SERIAL NUMBER 2797RK MADE BY MUNCIE GEAR WORKS INC. MUNCIE, INDIANA. IT LOOKS TO BE A NEW OLD STOCK MOTOR WITH LITTLE OR NO RUNNING TIME ON IT. THE GAS TANK IS SUPER CLEAN AND IT HAS GOOD SPARK AND COMPRESSION.
IT WAS FOUND IN EXCELLENT NOS CONDITION AND WAS BUFFED AND REPAINTED BY NEIGHBORS OF MINE IN A JOHN DEERE MOTIF AND IT LOOKS BETTER THAN WHEN NEW"
Where does he say that its an NOS John Deere outboard? It doesn't. Those are your words, not the sellers.
The rest of his drivel is just a boner-driven opinion of what many would consider to be a painted up conglomeration of dubious value.
What should be the concern here is that they claim it was an NOS original condition motor, and somebody butchered it with this paint job. Why ruin an NOS original condition motor? That part is probably indeed fresh off the stable floor. More likely it was looking pretty rough and somebody decided to have some fun with it, and this boob wants to pawn it off on some knowledgeable and unsuspecting Humpty for a ridiculous amount of money.
Hope this helps.
