  1. The salt has to be dissolved in the vinigar. After that you put the brass in and see the oxydation being eaten away in bubbles. (i dont know the mixture) I did put about 2 spoons in 250cc of vinigar. The brass looks like red copper as it comes out but a quick clean with brasso makes it nice golden again. This week i cleaned an old art deco lamp that someone had hanging outside. The parts were about 15 miniutes in the solution, than rinced under a running tap, dried and polished on the polishing wheel, shiny like new... Good luck.

  2. I have good results in cleaning brass parts without scratching them by putting them in an mixture of vinigar and salt. It even bites off green oxydation but doesn't damage good brass. But you have to keep an eye on the process and pick the parts out of the solution when ready. And wash them in water.

  3. Did find this strange radio. Apart from the dutch and french markings on the front there is not any marking on the set. The dial even doesn't have frequency markings on it but numbers. The hands function like those of a clock. The valves seem to be from the 40s. Could also be Civil Defense. Did anoyone see one of those yet.

  4. Hi Iain.

    Thanks for your elaborate help. It has  3 Mullard OC35 transistors in the front under the plate with the enamelled BCC logo. There a 5 cristals 4 by the relay and one under a grey cover next to the transformer. It looks very clean inside. But indeed i have to check the parts. I am a member of an local oldtimer radioclub but a transciever is something different. Transistors with intern cristal growth can be recovered. I did that already on an Sailor ships radio. I found out BCC made this type of equipment for Marconi also and it was used by the emergency services. It had a similar look but was painted completly in hammerite style silver-grey.

    Regards Fer
