[GreenKeys] Code bars

[CL in NC]

My son brought me a couple packages he found buried at an FAA facility, either Model 28 or 33 code bars.  One is a #192518, the other package #152552, pretty sure that these are TTY Corp. PN's  They were mixed up , I have 5 of one and one of the other.  The single one has two metal ferrules attached on one side, the others are flat and identical.  41 years ago I was working for the FAA and had TTY as a work load at a flight Service Station, and we also took care of the machines at 3 Navy base weather offices in Jax., FLA. We trouble shot and repaired machines down to the smallest screw back then.  Attached a pic, don't know if it will post.  If anybody needs one or all, let me know at this email.  Free for packaging and postage.
