Just uploaded a slightly revised Family Tree for the Homer group. Two additions made, first to the base 020 movement to include export models with ‘Unbreakabe Spring’ & ‘Water Protected’ on the dial – note that it is ‘Spring’ not ‘Mainspring’. See comments from Jay and me on the Hand Winders page: https://sweep-hand.org/the-hand-winders/#comment-578

Second addition is to the 570 Record Master movement – I’d left out the ‘Custom V2’ variant from the box.
