Any one know this Maker

[C Wallingford]

A friend has a 62 caliber trade gun and can't identify the maker.  The top of the barrel is marked OVERMYER in script and has London stamped on the top of the barrel. It has a beautiful curly maple stock. I do not know about the lock. Hopefully I can get a picture in the next couple of days
Any help would be appreciated.http://i557.photobucket.com/albums/ss16/cwknives/overmyerfowler_zps4fa4d704.jpg

Here is a not so good picture
