THANKS for response Tinker! I will have to look under the butt pad. If it had a steel plate originally I would have liked to see how it was styled! I have a few Katologs from the 20's and 30's and they offer pads just like this one installed on the rifles from the go. The butt is curved under the spacer also,this led me to believe it was at least installed by a skilled German gunsmith in the period. Any ideas on year of make? Kevin.
