Vintage Glass Coffee Grinder Catch Cup (bubbles in glass) Horseshoe base

Description

Vintage Glass Coffee Grinder Catch Cup (bubbles in glass).  There is a Horseshoe and 5-point star on the base.  Dimensions are 3-3/4 inches tall and 3-1/8 inches wide at the top lip.  There are various bubbles within the glass, and it's origin and "made for use" are unknown to me.  I used it for an Arcade No. 3 coffee grinder catch cup and it was a good fit for my grinder, but this is not the original catch cup for the Arcade No. 3.  Shipping is USPS priority mail within the Continental US.  Please ask questions prior to bidding.  Thanks for looking.
