Buckle looks good to me, and I believe the maker is Hermann Aurich, Dresden. Here is mine for comparison - note the design of the catch on the back etc. Others will comment also in time...
Look on backside under the right wing . There is the Aurich logo
its good,get better glasses James.lol.
Nice buckle James, and Aurich made, very typical Aurich with that short stubby catch and slender ears, the only other maker to use that catch is Osang but there tabs are big unlike the slender ones on the Aurich buckle. Can you see a year at all near the Aurich marking?
This is a good thread for comparison, you can see two Aurich buckles with Osang buckle, look at the three catches then look at the ears of the Osang buckle to the Aurich ones
