If you want to sell the Masi with a minimum of fuss and expense, pick a price that will please you and list it in the Classic and Vintage for sale forum.
You will get your money without seller’s fees and the bike will go to a grateful new custodian.
If you want to maximize the financial return, list the frame and fork with detailed photographs of all flaws on eBay - $700 or best offer.
Then offer the components as separate lots in separate auctions.
The amount of your return is proportionate to your time investment and the quality of your photographs and descriptions.
Be mindful that seller’s fees on eBay are not trivial.
Are you motivated more by financial gain or do you feel inclined to pass it along to someone who will be grateful for the opportunity to own a vintage imperfect Masi?
How you feel about the bike and its disposition will inform your decision.
Good luck with the sale.
