MERK-ERFURT

I was wondering if anyone had any information on a gun I have. It is an old, small caliber automatic. It has wodden grips and on the slide it has, next to some german proof marks, the words "DEUTSCHE WERKE WERK-ERFURT" I is a small cal like a 25 or 32. Serial number has the word germany above it and it is less than 50000. Just curious if anyone knows anything about it. Thanks
