At least if about antique (tube) tech radios...

I'm interested in assembling a tube IF strip if I find the IF trafos. Since I'm already made a pulse counting receiver with tubes 12 years ago, and now I have a bench mono RF/FM modulator, I can able to assembly one using normal IF stages. But the headache is to find these critters...
Well, I found 2 sites, but I wonder if it works, or if the sites are secure or active...

From mainland China. It seems to be used in some eBay kits.

From Gemany, but prices are not included and site seems to be frozen decades ago...

Anyone had some experiences with one of them? Or some shop have vintage 10.7MHz trafos?

Or also, if someone knows about NOS for quadrature detector (10.7MHz), I'm also interested.
