Information on Gunmaker 'Delcomy' in Kiobenhaven ?

[relic shooter]

I have this high quality .36 cal. rifled percussion target pistol by Delcomy in Kiobenhaven & would appreciate any information on this gunmaker.

Note;
The 'fly' in this lock is located in a very fine slot cut into center of the tumbler instead on one of the tumbler's outer surfaces.
The mainspring also serves as the sear spring.
The Set-trigger is also finely built & will fire set or unset.

Carl Heinrich Delcomyn was a Danish gunmaker. He lived from 1800 to 1864. He was a military gunmaker but also made many fancy guns for rich civilians. If you google his name you will get more information but you may need to learn Danish.
