Like some of you, I've also accumulated a drawer full of barrels, and I also mostly play older instruments. The barrel is frequently missing or damaged when I buy these instruments, and in most cases I can find a barrel in my junk drawer that works although it may not be as the original maker intended. Sometimes I've found a barrel that works only to find that when I later measure an original barrel for the instrument that it is quite different dimensionally.
I've made a few barrels to the dimensions of originals and they generally work well, although sometimes not as well as my junk-box barrel of different or unknown provenance. Tapered bores provide something of a problem, but there is one thing that I've noticed. If you measure the rate of taper, where there is a single taper, regardless of the upper and lower measurements they often correspond closely to the rate of taper of a standard Morse reamer.
There are other standard industrial reamer sizes and it may be that these will be represented as well. I'm sure that some makers have reamers made to their own specifications but I think these are probably mostly the specialist makers.
