Bogen LS-20 Before
Some pics I snapped and a video I took when I went home for lunch to listen closer after writing the above assesment. It seemed someone sprayed the grills with gold spray paint and did not remove the Bogen badge but covered it with tape. I removed the badge and cleaned them in the bathtub (left pic shows gold with black circle where the badge was, right still had soap suds when I took the pic). I returned them to black. Will post the oiled and restored wood next. The pics here show the dry looking wood but after I lightly sanded them and cleaned with a damp cloth. (Sorry about rotation, I will take future pics horizontal=wide).
