The bidding is already at top dollar for a project such as this. No radios, engine, or prop, and the right wing likely needs reskining/rebuilding and neither wing is original (there may be compatibility issues). Other damage is listed that may need repair. After buying what's needed to complete this project, one could buy an airworthy aircraft! If you bought the needed parts from Wentworth (expensive) you could buy 2 aircraft elsewhere!
I don't believe Wentworth would have this plane on Ebay if they could sell it otherwise (although they are new to Ebay and may be just testing the market.).
