The Red Raven Split is a beer I'm sure, the 3 is a mold number I believe. The swirls in the H.T. & Co. are from being buried where the chemical composition of the soil etched the glass, eating the softer parts, leaving the harder parts. At least that is what I learned years ago. That hutch is nice.
Thanks botlguy, I have wondered what causes the swirls in some I have dug, interesting. Some research call the red raven a beer/soda/medicine. Thanks on the hutch too.
