Nice, The small treadle lathe looks like a pre-WW1 Drummond (UK). Looks like it would still do a turn.
My grandparents used to take us blackberry picking on Sundays around Westbury. Never saw any lathes though! (Although Grandpa's shed contained a Drummond not much newer than the one in the picture, which is still in use in my shed today.)
Did they say where the larger lathes came from? Maybe from Phoenix Foundry in Launceston or the Railways?
