I looked at this and new ones and i'd say this is an older model. The new one's have a squared-off bumper and this buttcap looks older/yellowed. And the signature is much darker/bolder on new ones. That being said based on what Freddie has said its still hard to tell exactly where these cues have been made/assembled. Current version is the GB22: https://www.balabushkacues.com/cues/gb-series These are contracted to a Taiwan shop like KPS/KaoKao/KaoFa, all are capable of doing the work.
Balabushka GB22 pool stick has birdseye maple w/ 4 inlaid forearm & Ebony spliced sleeve w/ Mother of pearl inlays. It also has Nickel Silver & Irish linen Wrap
If not for the big ass ugly signature, these are very nice looking cues, I love the classic designs. If not for the sig. I might have pulled the trigger on a BG1/2.
I wonder how the play/feel compared to similar priced cues.
