I've dealt with tracking down stolen bikes for about 20 years and it's best to take each transaction on it's own "vibe". First it is rare that someone even knows the seial number of their bike (I've found that victims losing $200-300 bikes are more prone to know the serial number than those costing $1000s). Also I would never meet anyone at my house; I also don't understand hosting garage/yard sales but I'm pretty paranoid about prople knowing were I live. Saying this, there are a number of red flags with the ebay seller. First is the answer to the OP's question; I don't know any bike restorer that doesn't have before and after pictures; it's to show the quality of their work. There is also the seller, while having 100% positive feedback for 174 auctions, but with only 2 of those was a seller. Finally the seller says; I have been restoring bikes for 15 years and now focus exclusively on Classic Italian Steel Frame-Sets. Many other brands and sizes available; again, no before pictures and the Basso is the first and only bike frame he has put up for auction since 1999! That is an bad vibe one can articulate without meeting the person.
