Well, I think it looks like a 'seventies band photo anyway...
Inspired by Angus, my collection is as small although admittedly humbler!
top left: DW-9100 Riseman, module 1663
top right: DW-8800 Codename Cipher, module 1443
bottom left: DW-5600E, module 1545
bottom right: DW-6800, 1288
Of all those the 5600 gets the most "wrist time". I'm looking forward to my first screwback 5600!
