AiResearch t 04 information needed!!

Hi.
I've had an AiResearch t04 turbo come my way and I don't know anything about where it's from. If anyone knows where i could find a compressor map or any other information about it i would greatly appreciate it!

AiResearch T 04
model # T0445
A/R 100 on exhaust housing
Part # A42166

It looks like a pretty early design...
divided tang...

Thanks again! Any info is greatly appreciated.
