Mark Fowler, do you still have your Merrill 5549? I bought and restored an 1863 Merrill carbine, and the fun researching resulted in my creating a knowledge sharing website dedicated to James H. Merrill and his existing firearms - https://jameshmerrilltribute.smugmug.com. Please email me if you still have it, and if so could you please send loads of photos to share with everyone? Thanks, Eric.
