Here's a little fluff for your day. The following are results of inspection at chapter meeting and recent teardown of 4'9" /1,45m Brambach (pos) pso of unknown age. ---------------------------------------------------------- You know your pso has been rebuilt by an expert when... Top sections of hammers have been replaced but not the bass section. Hammers usually strike at least two of three strings in any given trichord unison. Hammershanks protrude through most (replaced) hammers 2 or 3 mm, those that don't are short by a similar amount. Una corda pedal doesn't shift action because both lyre screws and one leg screw extend into keyframe. Understring felt not replaced, but rather is covered by nameboard felt. Keys show no evidence of rebushing. Damper wires have some curious bends. Strings #3 and 4 go to the wrong tuning pins. Some pins at 5-10° toward bridge. Others angle left or right. Many pins show 8-10 mm thread above the plate. Bottom of pinblock shows most tuning pins poking through, and those you can't see are hidden by splintered bottom ply. Pinblock ends floating 8-10mm above inner rim. Plate webbing split throughout bass pin area. Pinblock fit "improved" by inserting 8mm thick pine wedge at notch, and using up to 8mm thick application of "Plastic Wood" between it and flange. Some of that application oozed up to 2mm thick on top of plank. Several plate screws bent by string tension. One plate screwhole so close to edge it looks like a "cut-away view". Have not thrown scale numbers into computer yet, but 14 unisons of 17 ga and 20 unisons of 13 ga., with no 13 1/2 or 14, will probably produce an interesting graph.
