Siemens Schatulle M 47 Tabletop w/ odd Markings

[solidjackson]

Thanks for all the replies. Fortunately (or unfortunately) no capacitors seem to have the markings like WIMA... most of them have the Siemens logo and are relatively small by mid-50s standards. One of the electrolytics on the 6BQ5 was off by about 20uf, so that isn't a good sign.
