German Aluminum Coffee Funnel

I believe these are from a restaurant or train. These are single cup coffee funnels with Bakelite handles.Price is for one complete funnel set; funnel with base, pour dispersing cap, and one coaster.These are unmarked except for the German on the coaster that says 'For setting down the filter' (Zum Absetzen des Filters). All are in good condition and just need cleaned.
