No fungus, no haze , no smell (!) and it should look near mint. If so it is worth a CLA, which is absoluteley necessary excepted the previous owner can proof it was done at least within the last ten years. AND the mirror must be o.k., a Maxwell screen improves the brightness significantly.
But to be honest I'd prefer my 1986 Mat124G. Cheaper , brighter, more comfortable, meter built in, lens on par with the Xenotar.
Rolleiflex is a different issue tho...........
