David,
I recently had a run-in with that "dealer" over another Smith he has listed, and was thoroughly scolded by him because I corrected him on the production date. My effort was simply to advise him that the date he stated was incorrect, and he proceeded to tell me that I didn't know anything about Smiths compared to him (he later corrected the date on the listing). If he would devote more time in researching his listings and less time burying errors in flowery prose he might have more buyers!
