E11s share the same keywork as the B12 (as they were both made by Schreiber), so they originally had unpinned or stepped LH levers and then went over to using nylon pins seen on Buffet clarinets in the late half of the '90s (as well as those annoying point screws with the plastic collar).
The stepped design is prone to becoming rattly as the linkage corks usually fall off due to there being hardly much surface area to stick them onto (especially the linkage on the RH E/B key) or they compress through use. The linkage arm on the RH F#/C# offers the key cork a bit more staying power as it's recessed into the linkage arm.
The lower end of the E/B lever on the ones with the stepped design is best silenced with felt or Ultrasuede to cushion it as it's effectively an open standing key, so needs that silencing material when it returns as opposed to cork or anything harder which will make a load of unwanted noise. The F#/C# lever will be fine with natural cork as that can be sanded down to create that necessary small amount of free play between it and the linkage to ensure the F#/C# pad closes. On ones with nylon pins, there's usually a disc of cork or rubber glued to a blind hole milled into the joint as the silencing material.
The nylon pins themselves can be quietened down with a single drop of thick key or linkage oil (do not use vegetable or bore oil), but you'll usually find the noise is also due to the lack of oil in the key barrels or excessive lateral play or wear which can be sorted out by any repairer who knows how much to swage them by so they'll be a good fit and still work but won't bind up when the humidity levels drop.
