Proco rat serial number dating

I did run across some great resources here and here that helped me to find out exactly which model and year this was made by considering the date of the potentiometers.

The number on the pot is R1379227, and as the 4th and 5th numbers are the date of manufacture, this one was made in 1992.

The distortion is produced using a variable gain circuit with diodes shorting the output to ground at a certain voltage level to produce hard clipping of the input waveform.

The LM308 chip is snugly placed on the board (Looks like a Motorola).

Across the potentiometers there is a sticker with the Dot Matrix Printed name “WOODCUTTER *” Apparently the WOODCUTTER was the nickname of the person who assembled it.

In particular, the op-amp and the codes on the pots (if there are any) are useful. If you post a pic of the guts, I can pin it down for you.
