Thought there might be a few in Ampersand's Staghound book , only a couple I'm afraid , both Polish . The 4" smoke dischargers look to be the usual British pattern seen on all sorts of AFVs . The comanders hatch was turned 180' and had the periscope removed , hinges to the front . Bow mg removed and plugged , sorry no info on the cable reel . Great book by the way , lots of prototype/ production Staghound ,T17E2 ( twin 50 cal ) and Staghound III, in combat and interior pictures , great price too , going for $15 last time I checked. Sorry thats all i got
