Default Brook 2A3 PP amp ID help

I picked up a mono, compact amp, 1950's, labeled only as Brook High Quality Audio Amplifier. No model number tag. It is in visually good shape, considering all the capacitors mounted inside. It has a plastic brief case handle on the left side for portability. It doesn't appear to use interstage or input transformers, but is capacitor coupled. What I thought was an interstage xfmr looks to actually be an enclosed choke. It has 5 input channels and various phono compensation modes. I'm trying to attach a photo but I'm not sure it will go through.

Brook integrated. Super rare.. (And probably quite valuable.) I've worked on the 12A, and some other models, but have never seen an integrated.
