Posted on this and had to buy it to get pictures to see what it is, who made it and for what purpose. The top of the barrel is marked "E REMINGTON & SONS ILION NEW YORK USA". Bottom of the grip frame is marked with serial number 465100 and stylized "R", left side of barrel "Cal 44", right side of barrel "NEW MODEL 1859", under the loading lever is just "R" and the cylinder has serial number and "R". Left grip panel has cartouche inside oval. Have not taken the grips off but can not find any other markings. I've taken some quick pic's, hope they are OK and see if anybody has a clue. Came out of an estate in New Jersey. I've exhausted every site with any info on the Remmy but nothing fits. I did see one site that showed one made for a Remington anniversary (don't remember who it was contracted to) but had a two line address on top of the barrel. Thoughts/ideas?
