Looks like it's all there, does appear to be a Dresda arm fitted from what you can see of it, goodridge front brake hose too.
Seems to have mileage on it (could be correct) with general state and corrosion to match. Needs refinishing of most components to get up to scratch with virtually all surfaces affected.
Depends on history and mileage once installed of "new" engine as to what's inside, but just from cursory outside appearances (if that could be in any way accurate to view it) it'll have a tinckly cam chain, gently flapping primary and stuck horseshoe to deal with, plus anything else at those miles.
Certainly looks dry stored, but put there without cleaning or preserving in any way. Likely a decent project but also complete strip too.
