What makes this a very rare Type S is the Deluxe option of factory engraving and stock carving that was offered by Mauser in 1930-31. Only 8 of these rifles have surfaced thus far. This piece was built up on a 1908 receiver pulled from inventory and coupled with a special half octogon half round barrel with full length rib. This option is described in Speed's first book on pg. 193. I found this rifle with period scope mount bases but missing the scope so I'm having Lee LeBas install period mounts to my 6X Zeiss and fit it to the rifle as shown in the mock-up photo. I discovered this piece at a large gundealer in Maine at 25% of it's market value, they simply did not know what they had. This post wraps up my collection for now so I hope everyone has enjoyed the show. I know there are great collections out there and encourage others to post them. Finally, I want to thank Mehul once again for all his help.
