Hi Zilverik,
Thanks for your input. I believe we are looking at an unidentified master’s mark 1725-? The Lion Rampant silver guarantee mark (1st) looks genuine too me.
To have something to compare with a photo of spoon, the date letter L (1745) and the rest, the maker’s mark is of Jacob Schenk.
Please note: Spoon; when the marks are located towards the bowl end at the narrowest part of the shank then they are termed "bottom struck". The process of striking the marks in this area caused the stem to bulge, so on return from the assay office the spoon maker would have to re-hammer the spoon often resulting in squashed marks that are difficult to read.Yes, you are right, the best way to examine the bowl is to use your eyes, triplet and having the item in hand, in bright daylight and a cool Foster in the other hand. Unfortunately for us Australia is too far away. My final advice shout be to have the bowl examined by an Australian expert on Dutch silver and to check the provenance of the bowl.
Was it forced or purely handmade? Are there traces of old workmanship? To my knowledge foot-operated lathe turning was available during the seventeenth to eighteenth centuries, so it is reasonable to assume that hollow, round tubular shapes would be turned in the lathe, cut to length, and other fittings soldered on. Hand raising was a skill used by the silversmiths. This was a process done with the help of the lathe. The flat plate metal was spun on the lathe and pressure applied to form the flat plate into a bowl shape. It would then be hand worked from there.
