I just so happen to own a Remington UMC model 10, actually it is pre model 10, they did not name this the model 10 until 1911 I believe. Mine actually has the dates 1903 and 1905 on it. But to get to your answer it stands for UNION METALLIC CARTRIDGE.
This model Remington typewriter is so common they have zero collector value so they are worth around $20 minus shipping... Unless it's one of the scarcer under-hammer models it's basically scrap metal.
According to Remington, it was made in 1913.
Manufactured 1922, depends on condition like new or used for a tomato stake?
100-1000 USD depending on EXACTLY what you have, its condition, box, accessories, papers.
1920
10, 108 of these rifles were made in 1976 only. Value if in "AS NEW" condition would be around $450.00. If you have the original box and papers included, you could realize another $100.00 from a Remington collector.
Most likely, the pump shotgun you have is a model 10. Uncheckered wood, grooved slide, value is from 150 to 300 dollars.
