Get a toothbrush, tire brush, sponge, soapy bucket of water and a block off 2 hours to scrub it down and dry it off. Toss a new front wheel on it, take good photos it against a bland background at kneeling height, list complete on CL for $450 and offering the original front wheel and $50 off for a no-haggle/no-hassle local sale. See what happens. May also consider listing on FB Marketplace if you're a FB user, OfferUp is another decent localized outlet.

Here's why you shouldn't use eBay: They favor the satisfaction of the buyer over the seller, so the seller can say anything bad and use that to extort you out of more money. As of 2018, eBay has started to nickel-and-dime sellers to death with fees and charges, some stick even if you don't sell: Listing fee, taxes, transaction fee, shipping fees, etc. It adds up to a good 10% or more you're losing, and you lose leverage on control once the item leaves your possession, and add risk with shipping.

This is just my 2¢. During the pandemic, bikes are fetching faster sales at slightly higher prices. While that's mostly true for ready-to-ride stuff, I've been seeing collectibles and vintage stuff that's $100 or so in parts and labor short of ready-to-ride selling at comparable prices. For every 2-3 weeks the bike is listed and regularly *bumped*, shave off another $20.

Main reason I wouldn't part-out is because you'll lose money. Very few people want the mostly-Delrin front and rear derailleurs, chances are they're cracked and inoperable so you can only sell for parts. Likewise, chances are the MAFAC half-hoods are shot also, as are the brake blocks. Value in this case would be a complete near- or all-original bike to be honest.
