Kr3019 opto interuptor specs

Not finding on Google search.datasheet archive, ebay.

Couldn't find anything either but it looks like a typical photo-interrupter module.
You forward bias the LED with a small DC current, likely 10-20mA, and bias the photo transistor with 5V, through a 50-100kΩ load resistor.
Then when the gap between is blocked, the transistor is off, and when not blocked, the transistor is on.

must be in house number..
Nothing else on it other than the date code from 1984 35 week.
I'm just sorting some parts and was going to put spec info on it..
I appreciate your info.

As a generic part, it's probably similar to these:
