Hi Basti
Both are the best of pieces you can find out there ... and would look nice in my collection as well

.
The DKiG is the earliest one you can find by St&L ... and this one seems to have a blackened wreath, which I have not encountered before.
The RK is definitely made by St&L - 1st pattern core - and with the lovely flawed "B" frame.
Price ... these will not come cheap ... but am reluctant to discuss money here ... have sent you PM on GCA already.
Grtz
Mathijs
