When I first encountered Abe's shop in Miami on a business trip it was 1995. I inquired around the area concerning the playability of Abe's cues. The consensus was that in his later years ( mid 80s to mid 90s- tops); he was still making a decent playing sneaky Pete. This cue here seems like a cue that Abe would have made mid 60s to perhaps later 70s- so anybody's guess on how it plays with a decent tip- if the shaft has reasonable straightness-- I personally love playing with older cues if they are reasonably straight and have a good tip - after all, experiencing how a cue plays is at least 60% of owning it- for me, anyhow.
BTW- that looks like a 70s era case- probably was with this cue for a long time- just an assumption. Also, Goodwill of Western and Northern CT- most probably ended up there on a home clean out for a deceased person- another tell-tale sign of the cue's age- definitely made before the 80s IMO--- this is an older area of CT where pool rooms were more populous until the early to mid 70s.
