Coins of Krolestwo Polskie minted in 1917

[monety]

Hi.
I'm looking for any information about first "Brandschutt der Stuttgarter Münze" in 1917 od 1918. Second fire destroy mint in Stuttgart in 1944. Why fire in 1917/18 is so interessant for me? Because in this fire almost all 1 fenig coins issued for Krolestwo Polskie dated 1917 was destroyed.
I know, in Münzen & Papiergeld 2/2005 was an article on 1 fenig 1917 (Jaeger 604) but wit no detailed information about fire. I have a specialised collection of Krolestwo Polskie coins with unpublished variants and errors. Any additional information will be very helpfull. For example, we dont know what was the variants chronology of 10 fenigow 1917.
Common, most popular coin (Jaeger 606a):

rare variant (Jaeger 606b)

Look on marked detail!
I've found a few other different shaped coins of Krolestwo Polskie. Hope, when will have acces to more information about Stuttgart mint history, will be able to reconstruct the sequence of events and variants.

Best regards
