AZ Aviation called me today. They are trying to locate a RH Model 23 wing. They have been searching under PN 169-110000-614, which is an obsolete PN. The correct current numbers are:
169-110000-664 (bare; no gear, ailerons, flaps, or tips)
169-110000-672 (complete wing assembly)

I referred them to Arrell Aircraft/Rick Leatherwood. I also said I would float an inquiry on MML and BAC, just in case anyone was aware of a salvage airframe. These part numbers were used on (or are replacements for) the following airframes:

-664
M0555-M1989, except M1971
MB001-MB865
MA001-MA368

-672
M0003, M0555-M1879, except M1875
MB001-MB816, except MB814
MA001-MA368

I have not researched what differs between the bare wing versus the assembly, that makes the bare wing have a wider applicability. This is a common occurrence in many parts, and it is probably related to things such as Goodyear versus Cleveland brakes; or the long AN6 bolt gear leg attachment, versus the Jo-Bolts (all should convert to the Jo-Bolts, when able).

At any rate, all that is really needed is the bare wing; but all leads are welcome. Please reply directly to the AZ Aviation email address, CC to me. Thanks!
