In case you could not find the originals, then search ebay for the hoods according to the filter size of each lens. Assume the 50mm Serenar has 40mm filter size; then search for "40mm metal hood". Different slot-type (Leica 12585) or plain models are available for prices less than $10 (from our Chinese friends), sometimes inclusive shipping.
