Chainsaw Repair

I got a 197? Jonsereds 70E in my collection in near mint condition,  all the decals are near perfect even
Its got a Tsumura bar on it with the painted letters still on it. I just put a raker file to it's rails and yup plenty hard, it's also got a nice old 3/8 Stihl semi chisel chain on it with straight verticle front depth gauges......do I keep this never used b/c just to look at or stick them on one of my work saws and enjoy it?

Speaking of tough hard bars the original German made 28" Stihl bar that originally came with my 1992 066 Mag Artic I'm  still running today on my 395XP. Longest running bar I ever owned.
