Not sure.
Possible imperial.
The one with the brown bumper is cool.
Same bumpers on early McDermott cues. I already have a couple brown or I would offer more for the bumper than the cue is likely worth. I am looking for those bumpers in colors other than black, brown, or green.
The blue pearl is interesting.
The Dufferin joint is interesting.
Nothing spectacularly valuable AFAIK.
