Inevitable the forearm and one or all of the shafts will be warped. That should be considered.
It is worth whatever the market will bear. 2k is a good price to start. I dont think an estate sale gets you the buyers, unless cue collectors can find it and bid live.
Needs a refinish. The Cortland linen line wrap can be cleaned up and left on. Any decent cuemaker can tape off the wrap when refinishing. Refinished it is a $2500 cue, so it really doesn't add a lot of value, but the cue deserves proper restoration.
