Mike, thanks for the info and another site to add to my bookmarks.

I had already it narrowed down to 1897 to 1924. I hadn't noticed the powder type and max load were only used from 1897 to 1903. That gets me close enough. That is also confirmed here. http://damascus-barrels.com/Belgian_All_Proofmarks.html

I wonder what powder is ECM3 and what kind of pressure was achieved with a 33 grain max load.

The bores measure as specified at proof and are bright and pit free. Who ever purchased this gun took very good care of it back in the day. I will do the same.
