Don't know what they are worth, but looking for the same answer. Have two in good working condition. Just love shooting them. Most people never seen one when I take them to shoots.
It can not be any older than 1907
The Fatal Hand - 1907 was released on: UK: April 1907 USA: April 1907
Stevens made the model 70 from 1907 to 1932 or so and cycled through production numbers of A 1 to Z 999 three or more times. Best guess (1932-1907 / 2 =12 : 1907+12=1919 ) Call it 1920 easier to remember. Hope this helps.
Depending on the condition of the firearm, on personal expierence i've seen them for around 200-300 dollars But my grandfather owns a Visible loader and its been apraised for 400 Dollars. Hope this helps.

As with many Stevens rifles of the first half of the 1900s, different reference books offer different dates of manufacture. It's usually accepted that the Visible Loader #70 was manufactured from 1907 into the early 1930s. It was last assembled from remaining parts in 1941 after parts production had ceased several years earlier. Sometimes called the "Miserable Loader," this gun can be found in good condition for $150 to $275 dollars. Ones with higher prices never seem to sell. Needing some work, they can be found for as little as $50.
