Mystery Parts Through the Weeks
April 19th
In reality the green and silver was the 603067-501 (horn assembly) which controls the ailerons in the yoke of the 2-seaters. This one was from the co-pilot side and is therefore an optional parts as listed in the catalog. The bronze bearing was a 'FF-911-3' bushing (of which there are two).
There were 4 correct entries all from Gurus (Ken, Ian, Garner, and Mr. Re) who also disqualified themselves from winning.
Thanks for Playing!

In reality it was the 5804008-501 (bracket assembly) which supports the pitot tube. This is an optional part (hence the 5904 start to the part number) as listed in the catalog. The 601 number written on the bracket was for those who zoomed in to read it to send it in. See Figure 40 of the AA5 series manual.
There was 1 correct entry from Ian who then guessed another part.
Thanks for Playing!

We have a winner: GAES 201 Honeycomb bobbin, GAES201-1: Mark Matthews, May 6th
Here is how the guesses panned out:
Honeycomb Bobbin - G/AES201-1 (AN3 - 3/16 th inch hole) --- ( 4 similar replies)
To easy. It is a spacer spool used inside the honeycomb anywhere a bolt goes through to keep the honeycomb from crushing.
Seat Belt Spacer - G/AES201-2 ( AN4 - 1/4 inch hole) --- (9 similar replies)
It's that little gadget (tiedown anchor or spacer) on the 4-seat crew seat belt.
Misc:
Looks like a thread spool from my mother’s sewing machine…No idea what Grumman used it for, however May, 7th
spacer block for wing root screw on AA1 C
Throttle bushing
Honeycomb standoff
it's a spacer between the honeycomb side walls where the wing walk bolts up to
