The Meriden revolver was made from 1895 to 1915. If you can't find parts at Numrich, http://www.gunpartscorp.com, then you're going to have to engage in a search of web sites, gun shows, really old gun shops, collector associations, etc. I do that regularly, and with the right attitude it's a lot of fun. Just don't expect instant success. (P.S., if the part is not visible you could have it made, but even in very good condition the Meriden is booked at less than $200 value).
10-100 USD or so
In perfect condition, $100.00
Brownells gunsmith and Down East guns are two places to find parts for the pistol. You can also find parts at auction shops and local gun stores.

Meriden Firearms was a subsidiary of Sears Roebuck from about 1905-1915. I can't locate a listing for a single shot pistol they made, but other similar guns from that time period list for $100-$200 depending on condition.
