He didn't say he would buy all of them, just as many as he can fit into the Tardis. There'll probably be plenty left. Maybe those purchases would generate more interest and more purchases (as the music store owner recounts how some guy just came in and bought every one in the store) so even more people start buying them (and then the store owner is telling how demand is so high he can't keep them in stock), and the company has to increase production. Popularity skyrockets and they become the most sought after instruments in that time period.At which point those Dobros and Nationals will cease to exist in the past, thus not be recognized as amazing so the companies will go out of business, and you’ll be stuck trying to sell unknown fakes in modern times.
Time travel is a bitch.
I think it could go either way.
Edit: I knew the name sounded familiar so I just looked up the Tardis. Yeah, it could probably hold a lot.
