Minolta 5 degree spot metering attachment

Hello,

I was wondering if any users out there have the instruction sheet for this spot attachment, either scanned, pdf or "hard copy".

I use the AutoMeter IIIF and have the 10 degree attachment, but I recently came across the 5 degree unit, real cheap so I did not pass it up.

Would appreciate the actual "instructions", but in the interim, any exposure compensation necessary, does the 5 degree work with the older IIIF, what are the 2 dots within the circle used for?

I know that with the 10 degree attachment, the single dot is the "eyepoint", but on the 5 degree there are 2 dots (distant and near eyepoints?, and if so, which is which?)

Anyway, anyone out there use this?

Thanks in advance
Ira

The lower dot is for near subjects to correct for parallax error. I have the instruction sheet, but it may not be handy at the moment, since we moved recently, and a lot of things like that are packed, but if I find it, I'll post it.
