They did do Pozi bits - they were a mottled blue in colour. Pozi screws appeared in the late 1960s/early 1970s
Have you got yourself an auger bit file to maintain your bits? Hard to come by decent ones since Nicholson stopped doing them a few years back. It was normal for site carpenters to have Irwin-pattern auger bits (stronger) whilst the bench (and hardwood) lads used Jennings pattern bits. There were other types used for drilling (ships) decking and starting a hole at an angle (Gedge bits), although I was taught a trick of using a centre bit (what you used on thin plywood, etc) to start the hole. You'll also.find turnscrew bits really handy - used with an electrians bit brace (about 6in sweep) they drive screws fast, but for torque you need to have one in a 12in or even a 14in sweep brace. For general use many trades had an 8 or 10 in sweep brace - and piumbers, sparkies and carpenters often had a joist ratchet brace for use with centre bits in tight spaces as well
I also still have my "egg whisk" drill - used for drilling small holes in plastics and metals
A tip about rebate fillister planes - pick the Record 778 twin fence rod style over the Stanley 78 single fence rod style. The fences stay put and don't change settings so readily. You can still get scoring blades (used for cross grain work) for both of those models, but not for other, older (defunct) tools.
Good grief! You'll be talking about shoulder planes, next
