Also on 1010s and Peter Eaton clarinets with that arrangement of having no crow's foot, the low E/B-F/C adjusting screw should be replaced with one with a much larger diameter domed tip where it makes contact with the F/C cup arm. They can be made with a regular adjusting screw with the head filed down (in a bench motor) and formed into a gentle dome, then the slot cut into what was the tip and then screwed in from the underside of the adjusting screw pip. You'll have to glue a disc of tech cork coated with graphite or tech cork laminated with thin a layer of teflon onto the top of the pad cup where the adjusting screw makes contact.

Similarly, the F#/C#-F/C sliding linkage on them can have a nylon tipped adjusting screw fitted to the linkage on the back of the RH F/C key to make the adjustment much easier. Find the point of contact on the underside of the linkage, then drill through and tap it to accept an adjusting screw.

In both cases, an M2x0.4 adjusting screw can be used - you'll have to tap out the adjusting screw pips accordingly.
