CSLs
Markos,
Firstly, ok, all CSLs were lightweight.........now let the arguments begin as to what degree etc
In simple terms, in deferring degrees of lightness, you have...
169 Carb cars ( CSLs) these are the first CSLs and are seriously light in weight. Not only did they have lighter gauge steel, aluminum hood, trunk and door skins, they did not have any of the comforts other cars had. They also had Lexan ( plastic) rear windows and fiberglass rear bumper. I could bore everybody with other items, but its safe to say, these were the lightest.
429 LHD Injected CSL's, in very simple terms, these were in many different configurations, but majority, including some with steel door skins, were what was referred to as "city pack" cars. Depending on what "options" the car had, weight varies. Very very few are what are sometimes called Ultra -lightwieghts, which would put them at near the same weight as a Carb car.
Then they made 500 CSLs for the UK market, as this car above is. All 500 cars were built in the same "city pack" specification, my understanding is they all had the 4 aluminum panels and while often thought of as the heaviest "lightweights" I don't know how a LHD "City Pack" with all steel doors compares to a RHD with all 4 Aluminum panels.
110 Series one Batmobiles, all Polaris silver or Chamonix white, but many different configurations and weights.
57 Series two batmobiles.......many different configurations and colors, BMW would let you order whatever you wanted. So some have steel trunks ( to accommodate the rear wing) and even may have steel door skins, so weight varies dramatically.
In answer to your question.
Yes, all RHD CSLs had chrome bumpers.
