the 62mm cap is too small?!?  Early versions of the 50mm Summicron-R use E44 
or Series VI filters.  Front cap # 14163 fits over reversed lens hood 
#12564.  Does this lens have a built-in hood?  The s/n makes me think it's 
an E55 lens.  If so and if the 55mm cap doesn't fit I suspect the lens has a 
Series VII retaining ring #14225 in the filter threads.
