Lachenal 20 key anglo Bflat F for repair. Serial number 181533 marked on both reed pans and both bellows frames. Nice set of steel reeds, free of rust and with no signs of maltreatment. Mahogany ends in good condition, pad boards have no cracks. Full set of end bolts, though I noticed two that won’t tighten. Bellows are fairly clean and look repairable. The main problem is one split gusset, but the rest of the gussets still feel soft and flexible. A straightforward renovation project. In addition to bellows repair it will need new pads and valves and tuning, cleaning and a new set of straps. With original case.
