This has been a good month for finding prime, vintage primes and the latest addition is the finest condition lens so far. This 1964 Mir-1 is perfectly mint and comes straight from Ukraine where it was made. It wears the badge “Grand Prix Brussels 1958” for which it won the title at the 1958 World Fair. I did have a few reservations about permanently modifying this near perfect lens but my purpose has always been to make this a usable set of vintage lenses and this modification does not alter the function in any way…
