My mother is selling her house and we're cleaning out and have an old CO2 tank (marked General Carbonic Co.) that my dad used to use to power his kegerator. It was in use as late as the early 1980's but Mr. Google has informed me that General Carbonic Corp has been out of business since the 1920s! Does anyone know anything about old CO2 tanks? I can't find anything relevant on the web. Are there collectors for this?

It's heavy as heck and scares me a little LOL.

Thanks in advance!
