Pulley bolt

The bolt has a shoulder that bottoms out before it tightens on the wheel. This is so the wheel may rotate freely. It has a whitworth thread and as such will not seize like a modern thread, - but it will be tight. Use a pair of good pliers or vice grips to give it a twist to help the screw driver. It only turns a 1/8 of a revolution whilst facilitating the gear cable travel as the rider selects btwn 1st and 3rd.
Wire brush it and clear coat or wax it and it will look great. They are very solidly made so you can give it some teddy.
The steel in these bikes have a considerable amount of chromium in the steel alloy so giving it a good brush or sanding gives a nice shiny finish that only needs waterproofing to stay great.
The same applies to the fulcrum clamp.
