Does anyone know anything about antique violins/fiddles?

Question by Tokosuki: Does anyone know anything about antique violins/fiddles?
I have what I think is an antique violin (or a fiddle) that I’m thinking about selling. The only problem is that I cannot find any information about the maker or the year it was made.
On the inside of the violin it says:
J O’Connor
maker
Waltham mass
No. 7

All of this is in a cursive script.
The violin itself is made of a very light wood and the head has been carved to look like a lion.
I’ve already searched the name and what I believe is the city, but couldn’t really find anything that matched up.
Does anyone have any information?
