Coin silver serving spoon question

[smackninja]

If you have any info on the manufacturer of this spoon, please let me know -- thanks much! The spoon measures about 10-3/4" long. I believe the maker's name is Schwartzkopf, but I can't find any web references to him (other than a passing reference to a David Schwartzkopf of Sweden, a smith from the late 18th century). My access to decent reference books on silver manufacturers is sadly limited. Again, your help is greatly appreciated.
