All right, folks, the nice antiques dealer returned with the glass lantern slide, and here it is. he also reported that he had purchased the slide for $35, and gave the change to me. I tried to give him $10 and he wouldn't take it. he said he had had a similar experience with another antiques dealer at one time. i think he liked the cloak and dagger nature of his task. if I see another glass lantern slide I like as much as this one, I'll buy that one too.
