This is definitely out of our area of expertise (kit came in a large collection). Box is exceptionally nice. It's dated 1955 on the side. However, a close review of the parts, you'll note that the catalog that's included is dated 1965. It's possible someone added the catalog later - or it's a later issue, of course. Research says there are 34 gray pieces - BUT I've counted 37 3 times. All 7 "window" pieces are present. There is NO assembly present - NO paint, NO glue. Should be complete - but buying As Is. Oh…and, yes, decal sheet is present - it's in the catalog in the picture!
