Mystery Part

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)
Its that little gadget (tiedown anchor or spacer) on the 4-seat crew seat belt.

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
