Is it normal to find a lot more SE razors, in antique stores, than DE razors? I stopped at 3 antique stores today and found all kinds of SEs. GEMs, Schicks, Auto Strops, some in VERY nice condition. DEs were much more scarce though. Is this common? One thought I had was that DEs are more recognizable to non-wet shavers, so the SEs end up getting passed over.
