Identifying Value: German .22 Rifle - Dormant Lion?

Question
I have had this 22 for some time,debating on whether or not it is a wall hanger or something of value. It is a single action with a pin to pull which open the breach and ejects round. On right plate has D.R.P. Germany, on top of the chamber has a marking of what looks like a snake and a 1 and is also engraved in a slightly raised logo on the stock. Looked a little on line and came up with dormant lion. Wall hanger or something of value, condition good cosidering age. What do you think?? Thanks Jason

Its worth $100 to $300 depending. If the inside of barrel is in good shape it may be a track driver. These were made to teach marksmanship.  There is starting to be some collectors interest in these.
