Polyurethane Finishes - on products

[Isaac OLEG SIMANOT]

Hello,

I just called to find some black dye, and find what is called here NIGROSIN,
it is alcohol soluble, and is sold by small 20 g quantity, price €9.37 . I
will forward you some if you wish. It is a "fushine"

The Furniclass we found is actually made in France in 2 quality (no additive
tint) blond and clear.
The price is high : 38.42 € litre.

The London firm stopped the fabrication once told me .

Sure that the Brodwood are very nice pianos.

In French "recharger le tampon"

I forget to mention the most important product used , is what we call "elbow
oil" ;>)

I've seen strips of felt bushing from Baumgartel today, it is not as the
good traditional "casimir" (you know that reddish felt we used in the army
to make the "zouaves" pants) , but it seems Ok for bushing work.
