Can't see what's in the bag but from the remains, you have got what could be a perfectly useable/serviceable tube. All of the optics - if you have them from the old cut-up No42. And the old No42 inner OG tube can be simply converted into No32 spec. All you need now is the deflection cursor slide and graticle block and nut. And a set of drums.
It shouldn't be beyond the wit of a good turner to make a set of drums but....... If he's doing that then just machine a simpler set of Mk3 drums instead! By next Thursday I'd have a Mk2/1 in my hands
As a matter of interest, what IS in the bag? Looks like a centre axis rod and sleeve from a pair of No2 binos to me from here!
