Wonder if anyone can help I have just bought a airbrush on ebay it is a
ROYAL SOVEREIGN model RS-703 I have been unable to find any info on this make or model.
It looks like a IAWATA can't remember the model but it has a fairly large cup and is dual action. The body is all metal silver in colour.
What I need is either a thread adaptor or full air hose but I do not know what the thread size is. It is not a 1/8 aka Badger but larger. If I measure across the width of the thread it looks to be about 3/8 inch.
The only adaptor I have been able to find is a 1/4 - 1/8 not yet bought hoping someone can confirm what I require.
Many thanks for looking
Pete
