Sheaffer Factory Double “Paint Screen” used for painted finishes on Prelude Pens. Measures 14 x 7 inches. All steel, the two screens can be removed from frame, each screen measure 6 x 5.75 inches. I remember touring the Sheaffer factory and seeing this in action machine where a worker managed the painted finishes onto Prelude pens, it was really quite amazing. The two individual screens can be removed from the frame. Note the photo which was taken in our kitchen, we mounted 5 screens for a little industrial art in our kitchen!  (8 available)
