I do have the Diamond Tour putter head. It looks like an Odyssey 7s, but IIRC it has more loft and heavier head for an armlock style putter. It says Inazone ArmBar on the sole.
Also found some other mallets laying around: Mentor V-MOI Duet, Never Compromise GM2 and a Kirk Currie Rio Grande. There are probably others gathering dust, but these were the easy to see ones.
