My original Bottecchia Special, which some would call entry level while others (like me) would call lower mid-range came without turkey levers, pie plate on the chain rings, or stem shifters. It did have a discreet clear plastic dork disk similar to the one shown in Bianchigrl's picture. I left it on until the early 90's by which time the formerly clear plastic disc had turned yellow and opaque from age and scratches so I tossed it when I changed the freewheel.

Really though, I ride vintage bikes because I like the way they look and how they remind me of simpler times gone by and the turkey levers, pie plates, dork disks, etc. spoil that look and feel. If you don't care about such things then by all means leave them on. I've actually considered putting a set of those modern, inline CX brake levers on my Peugeot because I use it as a pseudo cross bike and they would work a heck of a lot better than turkey levers. Come to think of it, a big pie plate on the chain rings can really come in handy on your commuter if you ride in long pants. I have to use pant clips on my Panasonic to keep my work pants out of the chain so I wouldn't mind having on on there if it was decent looking.
