I have to say that if I had the full 50th Groupset minus the dustcaps I'd be happy to have the option and they are sold as repro.
Also on the subject of pattern parts not carrying the original maker's logo; that's true and not at the same time. If, for argument's sake, I was restoring a Triumph Spitfire and I bought a pattern bumper I would expect it to come without the Triumph stamping. If on the other hand I needed a replacement badge for the bonnet, it would. Those guys who have a whole business in replacement decals make reproduction parts all of which have the original maker's logo. To me the dust caps are a but of a crossover component. It's almost like a replica badge, but similarly they could be made without the badge and I'd be happy to have them.
