Well Will, just happen to have one myself. Mauser 98, DSTs, sporter stock, no scope etc.
was discussed here on NE about a year+ ago. Not made for very long after WW1 (about 2 years)
in the Danzig Arsenal so not many around. Do a search in Mauser Archives / Mauser discussion you'l find some pics. and chat. Post a pic. of yours, it always helps with the ID. --- John
