On your way to Dayton, you should drop by the Carrousel Pipe Shoppe in Cincinnati. It is located within 3 miles of I-75, off of exit 10b. I just posted this in the trade forum Sunday:
My friends at Carrousel Tobacco Shoppe, 8001 Reading Rd, Cincinnati OH,(513) 821-5350, just received a large collection of GBD pipes as a part of an estate. The man was a serious collector of English pipes(with the exception of Dunhill) and traveled the world as a part of his work(he payed Cello in the Cincinnati Symphony). He was a friend of the Carrousel and his death was heart felt. So far the Carrousel has received from his estate 75+ GBD, 100 James Upshall, 50+Ser Jacopo's, 25+Comoy's, 8+Charatan's(Lane era mostly) 3 pre-transitional Barling's and lots of others. Most of the pipes he collect were large-extra large. Today they've asked me to list several of the GBD's on Ebay(under username JEGLWAR). Please contact Arnold between the hours of 10am-5:30pm est if you would like to learning more about the collection. I can send requested pictures of pipes of interest for them(they are both not interested in computer whatsoever). Just mention you saw John's post.
