Have you checked in w/ today’s Botnick yet Bill, 100+ years in operation!

Please update w/ details of your car, Coupe or Roadster + Engine/Trans/Color also Build/Sale dates and I’ll take a look for Old Newspaper Ads. It’s doubtful anything’s there as most Botnick Ads are shared w/ other local dealers as below but still worth a whirl.
