Hi! I just bought a Domestic Treadle this week and want to restore the machine and the cabinet. I can't find the thread about restoring the cabinet and was hoping someone could point me in the right direction. Also, once I take the rust off the 'shiny' metal parts, what is protecting it from rusting again? The Brasso? Or just routine rub down it machine oil? Will cleaning the rust off remove the engraved numbers on the front bobbin plate? (Some kind of chart?)
