Principia Rex 1995 reach and stack

Hello,

I have a Principia Rex from 1995 (my best guess). Is there anywhere where I can see the exact reach and stack of it? I can obviously use a measuring tape but then will not give me the precise measurements.
 
These measurements didnt start being used until quite recently (mid-2000s i think), so i doubt they'd have been made by the manufacturer. Anyone else would just be getting close with a tape measure like you

www.bikegeo.net has a calculator if you have detailed geometry. It seems to be fairly close from a couple of frames whos numbers i've plugged in

The thought actually crossed my mind that they weren't invented back then.

Thanks a lot for the link! I'll see if I can dig out the exact numbers and plug them in. But if say yours are fairly close then that is probably as close as I get.

i put in the numbers for my kinesis T2 from the kinesis website, it was with 2-3mm on both figures of the official kinesis number
