The bow pulpit does not match that of the Luders 33. But that could have been changed many moons ago. But I agree on the topside pin stripe. I once found a webpage with manufactures topside pin stripes but cannot find it anymore. I think back then, not only the logo on the sail ID'd a boat, but so did the topside pin stripe.Sure looks like a Luders 33 and most of them were built before HINs were made mandatory. The roller boom furling along with other features, dates it to 60-70s vintage.
