RP - Agreed two exceptional condition firearms. Both lacking serial numbers make me wonder if they were part of the Remington 1949 sale. Do they have either a brass tag or marks where the brass brads were holding the tags. See the previous post. The issued Cuban carbines have a serial number just below the Cuban Crest. See p.61 of the book. As mentioned before some 2,600 carbines and 400 rifles were sold to the Cuban Government. The carbines went to the Rural Guard and the rifles to the Artillery Corps. The Lees came back in 1913 -14 to Remington where they were refurbished and 1,153 carbines were sold to the French Automobile Corps in 1914. The refurbishment included polishing off the Cuban crest, rebluing and woodwork. A straight edge will show a slight dip of 2 -3 thousands where the crest was polished off and a bright LED light at an angle sometimes shows the faint outline. Also my refurbished rifle shows slight pitting along the wood line. The refurbished arms have a small proof mark, RP in a rectangular box, on the right side of the barrel just ahead of the front barrel band, see p.62 of the book.
Your rifle has the later fittings found on the Model 1902 Rolling Block which were used on the Cuban Contract carbines and rifles. The rear sight base is a variant of the Michigan Model because of the more rear placement on the barrel. That bolt interrupter is made of soft steel and usually is missing or badly bent.
I wonder if the dealer has any info on the previous owner(s) of these arms. Bruce Stern had a number of the Remington Lees, including several factory pieces. I know he documented his arms as we chatted a number of times about his Lees. He had picked up several of the factory pieces from a dealer in PA just days ahead of me. There was also a collector down south that aquired several of the factory arms.
