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

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.
