A 1930's Thermos food flask.

This item has been with us for some time.

Painted in brown crinkle paint, much of which was rough with rust, a difficult decision was what was to be the best course of conservation.

The exterior was prepared using a soft rotary brass brush and the nickel plating was cleaned with Phosphoric acid.

The exterior was coated in lanolin and polished, tinted with a small amount of brown oil paint, I think it now looks great  and another fine exhibit.
