I'm in the process of repairing and refurbishing a 1953 Murphy A192

I assume the case is Bakelite with the front panel finished in a sprayed satin ivory / cream colour.

The Bakelite has developed a whitish bloom, especially the top surface.

In the past when dealing with brown Bakelite I break out my tin of liquid Brasso and after a bit of hard work the Bakelite looks like it has just come from the factory.

This Murphy's case is another matter altogether. After four hours of polishing the top of the case it doesn't look much better apart from the surface looking a bit shinier but the underlying bloom is still there. Normally when cleaning Bakelite I notice some transfer of brown colour onto the cleaning cloth, but with this case only the colour of the Brasso can be seen on the cloth.

Could this case be an early type of plastic and not Bakelite? if not can anyone recommend a product better than Brasso to bring this case back?

Thanks for any help and recommendations.
