I really can't see, in everyday use, the point of sprung buffers. OK I have a couple of models with them, but to my mind the only reason you really need them are if you are using three link couplings, or intend to run right up to the buffer stops (highly unprototypical).
As the class 121's rarely, if ever, ran in multiple then the question of sprung buffers is even less relevant.
I believe the latest versions of the 121 now have NEM pockets and close couplings.
Unfortunately when you buy old Lima models you going to have the inherent Lima problems.
