QC & RA added. PITA was already on list.
Thanks for the additions
Sorry- I missed that!....what a pita, pita was already there!
In my defense I was hopping back and forth, installing some Q decals and then checking posts.
Ok, as a semi-redeeming shot, here's some that actually aren't on your current list;
-"Q" a term with burlington folks for the CB&Q..not widely spread among the community, but hey.
-"TLR" that looks right... a term for scratchbuilders or kitbashers on how close you got it to where you wanted it.
-"PE" can also mean photo etch as in etched brass detail pieces.
-"PO" can also be previous owner when describing used items.
