barry szamboti will look at it and do a letter if its real, its expensive bit pure gold when it comes time to sell the cue,I own over 40 szamboti's. the other poster who siad that barry(gus's son) isnt doing letters is mistaken, if you contact Barry by email at:
blscues@comcast.net and tell barry in the email you were referred by Eric Petersen he will reply to you. by the looks of the pic I think your safe-but the letter is what you want, mention to barry and give him a link to your thread that will help.
best
eric
