Wanted: Genuine Marshall organ pipe whistle

[Marshall Mad]

Does anyone know where I could get a genuine small (patter no.7) Marshall organ pipe whistle with inclusive valve?

The ones on Heritage steam don't have the valve included and would prefer an original

Thanks,
Ben

I have several small O.P whistles that might be what you are looking for.
Can you give me the diameter and height you want.
Photographs are on my other computer.
Can get me on coalburner@btinternet.com

theres a whistle currently on ebay that isnt advertised as Marshall. But it is a very close. Dare I say it 200% better than the 'Heritage' item. Which isnt any sort of copy.
