Have owned Who Dunnit for two years and ready for a change. Very good condition, everything works well including slot machine, no credit dot. Would like to trade for another Williams/Bally DMD game with plus or minus cash. Interested in No Good Gofers, Indy 500, Corvette, Congo or possibly others , all with plus or minus cash. Will exchange pictures and details if and when an interesting offer comes up. For obvious reasons needs to be a local /GTA trade. Thanks.
