Lunati Pro Series 4.250. STD/STD. Has 1 medium size piece of Mallory on the front counterweight for balancing which will make your balance job easy next go round. Ignore the fluiddamper in the pic unless your interested in it.
Lunati cut the counterweight on a taper to reduce weight, this is done in house by Lunati and is a $250 charge by them.
Selling for half of what new costs, I talked to Lunati yesterday about their current pricing. If you give me your bob weight I will balance it for ya cheap or free if it comes in fairly easy.
