Maybe the other way around. Seems like even a Sinaron lens cap once cost more than the average Leica. Somewhere I have an old Sinar
advertising plastic clothespin to hold up something - maybe signage or corners of a darkcloth - who knows? But it should be worth several
hundred dollars on EBay with the description of "RARE", "collectible", "genuine Sinar object prior to wimpy little Leica acquisition" etc.
