@HB Chris It looks to me like the actual tray from the early E12, E21, E24 is the same size and shape as the late E9 tray and would fit where the E9 tray fits. The difference is the tool selection. Since the spots for the tools are molded into the tray the actual PNs would be different for different tool sets. I think you could mount the 71111117105 tray (and possible others) in a late E9 if you were not that concerned about the originality of the tool set.
