Bubba YOU got some really neat old well made stuff...I'm still using my Lyman M5 scale - but your box looks in better shape than mine. M5's IMO ARE the THE top of the line Balance Beam scale, and I have couple things put away like the nut cracker style primer seater & the brass length guage - but I still got rhe cross piece to mine somewhere....I hated that bullet puller in the red & blue box after chasin either the cap or the little metal bullet holder inserts all over the garage. I'd bet my RCBS metal cased lube pad is older'n yours though....and everything from back in those days still works great.
Wish I had the bux and space as I'd buy most of that stuff just to play with again.
