My fourth and for this time last 57-er EK2 is this early S&L marked "4". It was nearly as expensive as 39-er, but I am happy to have it. On the second photo you can see the comparison between late S&L (left) and early one.
In "happy hour" I purchased this EK1 S&L in case (halbetui) that is probably wartime leftover.
This stonemint piece was stored in bank vault before I bought camera, so I can offer you only old seller´s photos. Sorry for that.
...and for this time ended with this Ritterkreuz with first pattern core. Some say it is "C" frame, some say it is "D" frame with leftover first pattern core. Personally, I would be hapier with second opportunity.
Finally I focused on finding some nice oaks and OLS. First were these late OLS with different silver content. Oaks are die struck and marked ?00 (first numeral is under the loop), swords are cast and marked 925.
