Antique Bartlett hand crank sewing machine. Rare 1860s For Sale

What I could find out about this machine is that it is a very rare Bartlett handcrank sewing machine that I have restored. It sews with a looper and sews a good chain stitch, it has a new looper. These machine where made from 1866 to 1870 only 5,000 to 6,000 where made. The serial number is stamp on the cloth plate on the under side, it serial number 2167. The hand crank turns very easy and works good. All parts where cleaned and polished, the paint was removed and repainted and after new decals where put on it was sprayed with clear paint to seal and protect the decals. If you collect these type machine this is one to get, it is the first that I have seen. The wood base is Alder wood with a Early American finish on it. It has new felt pads on the bottom to protect the table tops. I ship International. Questions welcome.
