Close! I have a 4-point Hoppe Tad w/flat-face stainless joint w/big pin that is 58" w/balance point at a hair over 20". The butt is around 14.2oz and matching full shafts at 4.575oz. The only issue for you is it has a linen wrap. But, the wrap has been cleaned and smooth to feel closer to wrapless cue than one w/a wrap. Everything straight and plays great, these shafts are extrodinary.
If you are looking for an inexpensive wrapless w/forward balance, I also have a Russ Espiritu ebony w/curly mayple handle stainless piloted joint & 1 nice shaft. Very nice crisp hit. The butt is 14.7 oz w/weight bolt & 13.8 oz with it removed. When the weight bolt is removed it is very close to 20.5" balance point. Straight together and apart but there is a finish flaw near the collar. Will price accordingly.
If you are interested in pictures, please PM me your email and we can go from there. It is so close to what you are looking for I had to post it.
