Tiny Twin

The tiny twin engine, ME 4532 p590 shows the boiler bushes made out of brass. Is this ok on a copper boiler.

I can't see where it says make them from brass? Photo 2 clearly has them in bronze.

On such a small boiler that is unlikely to get much use and has a very low WP they should bot be a problem if brass were used and they are above the waterline, seems to work OK for the likes of Mamod.

More interesting is that the material for the copper boiler on the drawing is given as 10-20swg Brass
