It's also fascinating when you consider the specs necessary for lighter barrels and sub gauges. I've done several Heuse Riga-Fils sub gauge sets, the taper and proportional sizes of their 20 and 16 gauge tubes (small scroll 2-iron) are wonderful. It goes equal or more so with small frame Parker sets, and they're even more complicated 3-iron.

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
