Howdy,Chris!
Hey! those instructions look like those from My Polish destroyer. Oh, By the way My destroyer is Cardstock with P.E. as well. Yes -1/350! I have most of Dragon's ,what I call small ships and their equals in Cardstock. Same level of detail even to hatches you fasten to the Bulkheads.
Thank You for the effort you have put forth here. T.B.
