U101 RRR amplifier knobs

These are copies of the U101 amplifier knobs from their original appearance. It doesn't fit directly on the rheostats, I need an extra sleeve, which I already had. But I haven't drawn it, only the knobs themselves.

Those who have been dealing with a U101 amplifier already know what it is all about. I think these can be used by others, just need to print a compatible sleeve, because the diameters of the rheostats also vary.
