Lee,
I love the looks of your Walker! I do not own one, but I am entertaining a repro 2nd Model Dragoon. I already have a fantasy Pietta 1851 Navy Dragoon .36 The 1851 Navy brasser is a .44: not my kind since I do only .36 Navy repros. Nice looking but not near historical, sir.
I want a repro Dance and Brothers .36 based upon an 1851 Navy frame, preferably Pietta so I can exchange parts. It does not look like it will happen soon.
Jim
