Helpful folks replied to let me know it was an Ashford Traditional. By looking at the timeline on the Ashford site, I concluded it was made between 1965 and 1975, just like me! It has a three-knob spoke, simple uprights. and leather bearings. :) Must be good, made in that timeframe! Hah!
I spun two bobbins full of singles, two ounces each, and I'm ready to ply. I'll try the larger flier for the plying... The small bobbins seem to be full with the two ounces on them.
