Not many of those around, I know I own one. It has MOP above and below the joint like yours as well as a MOP butt cap. Mine is a full splice 5 veneer Spain blank. Interesting to see the aluminum insert on the shafts. I have 1 original with that as well.
Is that an aluminum Weight screw? I don't know if you've ever had it out but mine is aluminum and 1/2" diameter. The screw is threaded inside if you want to add a steel screw for more weight. Not to interrupt your sale but I thought I'd compare notes.
Good luck with the sale. Its rare to see them and as mentioned fits right in with Palmer and Paradise cues.
