The C.S. Shattuck Arms Company was located in Hatfield MA and was in business from 1878 to 1908.
Shattuck guns have little collector interest, from what I understand.

All the history of Shattuck I have been able to find was listed above... you might try searching some of the gun auction sites to see if there's one on the block and see what it brings.
