Antique Coffee Grinder with Original Cup

The classic Arcade Golden Rule Antique Coffee Grinder in untouched, hard to find near mint condition. The face plate is iron and has a very nice dark even patina with no staining whatsoever. Pine wood box with tongue and groove construction, also in exceptional condition. It is missing the tin lid at the top which is common. The paint overall is in excellent condition except for a small lighty worn area near the end of the handle and some areas of the pull ring. The handle itself is very tight and has a rough texture. The backboard has a mark 19910 hand engraved behind where the catch cup sits which would be its Arcade model number (rare). This antique coffee grinder comes with the original cup signed Arcade on the bottom of the glass with tablespoon markings.  These original cups are getting harder to find and command prices upward of 200 alone.
