Where can I find pictures of accordians to identify and appraise mine?

I bought an accordian. It is full size, 41 keys, 120 buttons, says it was made in Italy with a serial number:2364. It has no brand name on it anywhere, just a crest...red, blue and gold, with musical notes on it. I can't find anyone like it and I've looked on many sites with many pictures on web. I want to get it appraised and sell it but I don't want to get ripped off. That's why I'm trying to identify it first. Does anybody know of a site I can go to, maybe with a zillion pictures of accordians?
