Brake booster vacuum check valve source

[John Maglia CLC#23063]

Does anyone know a supplier for the vacuum check valve for the power brake booster on a 57 Coupe de Ville? I've checked the internet and eBay but have come up empty. Any leads would be appreciated.

Thanks

Same here John for the 58 and 59 Cadillac....I've searched and searched and come up empty.  Some of the usual places actually list them, but they are wrong as their parts are generic and only are for the valves that mount to a more modern day booster housing directly......sure could use a new one for my 59

Anybody with a source?

From John's picture, it appears that the check valve is a 90 degree fitting that is in line between the manifold and the booster.  I know of no source for a metal valve.  There are various other plastic check valve's that are available but, alas, don't do much for authenticity.  Perhaps a new one could be masked to look like an original.  Power Brake Sales in Sacramento, CA  would be a good source to check for a new type valve.  www.powerbrakes.com

Maybe this can work?
