Wow, anarchisthermit! Those cobs are beautiful! This is inspiring! I'm going to start doing this to my cobs. Is this just by allowing dirt from your hands to stain the cobs? Looks like you've got a lot of vulcanite stems on those. Are they forever stems from Walker Briar Works?
Those don't look like they've been smoked recently. The wear on the stems looks like they've had enough time to patina over with oxidation. Is this just a display of yours? If not, I bet that white oxidation on the stems tastes nasty. I had an old Grabow passed down to me that had white oxides on it like that. It tasted like machine grease and rotten egg.
Looks like ya got all wood bottomed MM's. Only two original stems? I see Diplomat, Danish spool & Egg, General, Patriot represented. Nice lot of smokers right there!
