Solartron 7081 With Bad WR057 Diode

My Solartron 7081 has a bad WR057 diode that needs to be replaced. It's
a three terminal device that looks like two silicon diodes in parallel.
It was making the meter read about 10.1V with a 10V input. Luckily it
was temperature sensitive and was easy to find with freeze mist. Removal
caused a shorted input to be about 2.5 microvolts high and a little
noisy. I've not been able to find this device on the internet but
thought that someone here might have seen this thing before.

I might be worth asking eBay vendor LittleDiode, they are the eBay shop for LittleDiode Components ...
