[CR]looking for a cottered left crank arm

Fellow listmembers, I have put some pictures of a mystery right cottered aluminium crank arm in my wool jersey album. It came with Simplex adaptors and steel chainrings in 48/52. http://www.wooljersey.com/gallery/Drexl/Parts/IMG_4396.JPG.html The design is somehow similiar to a legnano crankset is spotted on Mark Bulgiers excellent website here: http://www.bulgier.com/pics/bike/Parts/Cranks_Pedals/LegnanoCranks/Legna no_crankset2.JPG My crank is fluted and made of aluminium, the fluted part is laid out in blue paint. I would like to use this set as a period correct set on my mid fifties Cinelli B model to replace the upgraded campa record set, but i am lacking the left crankarm. Length is 170 mm. Does anybody know what brand this crank is and does anybody have a matching left cottered and fluted 170 mm crankaram? I know chances are more than rare but if not here....... regards Michael Schmid Oberammergau, where we finally got some snow for skiing....
