Mercedes 200 lang cabriolet B 1935
2014 Chrysler Classic Day - Boxtel (NL)

This car was identified as a Mercedes 200 (W21) cabriolet B from 1933 by the Classic Park museum. Since the cabriolet B body was only offered on the long wheelbase ("lang") chassis which was introduced in 1934 and the car has skirted fenders which were introduced in 1934 for the 1935 model year, I think that 1933 was a typo and should have read 1935.
