Very large, very heavy. Lens coating can degrade and yellow while aging.
B&Ls have either a black body with a silver locking ring, or a silver body with a red locking ring. The black ones were the later models, and it is reported their coatings do not yellow/age as quickly as the earlier models. Discoloration over time is inherent due to the B&L coating manufacture, exacerbated if the lens was used with a xenon projection lamp. The date the elements were ground is stamped on the inside edge of the front element, if you hold lens at a right angle and observe the element’s edge it is usually faintly visible.
