The lower left hand lens in your "kit box lid" looks to be for all the world the Helios 44-2 58 F2 lens , which is the one I will be converting for infinity focus for Nikon F mount. On Canon body the registration distance should allow infinity focus without modifications with a cheap Canon M42 adapter...........I also find it strange that this lens was not sharp on your body............Could there have been an extension tube in the mix?
