Today's forgotten corner is triggered by Mystery Objects. As far as I know the hard waste condenser spinning industry in the UK is dead, The yarns they produced are technically different than those in normal spinning, one characteristic being that they were very soft and excellent for raising to make cloths like Winceyette and soft dusters. If you have a look at the LTP and look at spinning at Spring Vale, that's condenser spinning and you can see the whole process which as more allied to wool spinning than cotton.
Machines like the 'Jumbo' hard waste breaker above and the 'Devils' above that were fearsome. The Jumbo could break up heavy cotton rope and the devils regularly caught fire they were working at such speed. Well worth looking at and as far as I know, all gone now.
