Well, I don't know anything right now except that I own it

he accepted my $75 offer from his $150 original buy it now- I hope to have it by Thursday. My original Dufferin" made in Canada " BF cue- which the photos are posted up above- also has that same bumper-only with "made in Canada" stamped on it.
I am also starting to think that this cue I just purchased- the ADAM- may have been made by Dufferin Canada for ADAM- if that rubber bumper has a removable rubber center and if the screw holding the bumper matches my Canadian cue- with a square head - that would be one clue. I can also inspect the glass window and the butterfly splice to see if they are a match in certain ways to my Canadian Dufferin- that would be another clue.
Maybe this cue that I just purchased is nothing more than a Chinese ADAM copy of the original Dufferin butterfly cues - But maybe it is a very rare find of an ADAM Japan cue made by ADAM Japan or made by Dufferin Canada for ADAM Japan - it was worth $75 to me to satisfy my curiosity- I think that I could always sell that cue and case to someone for my $75 if it is not what I am hoping.
The 3/8 10 pin is, to me, the big mystery here, was a new shaft made for this cue and the original butt joint altered- well it was an estate find in Nevada according to the seller- so maybe the answer literally lies buried somewhere now. And that case - I never see mint condition looking cues in mint condition looking cases like that unless they are 80s to mid 90s cues.
So I am just having some fun with this one- just one of my many interests and hobbies- thanks to all for sharing your thoughts- much appreciated
