Charging issue

Even the casing screws are cheeseheads.

I think you'll find they are Fillister Head screws

The correct ones have that curved top. Cheesehead have a flat top. I was only able to get a mixture of Cheesehead and Fillister head screws when I was restoring my engine.  Glad you don't have Allen screws! :)

Genuinely didn't know they should have a curved top (Fillister) - certainly news to me.  When I was restoring my bike, I asked the fella who was helping me with the engine to get the right screws, and he got cheesehead (flat top).  These were supplied to him by a specialist BSA outlet - hmmmm.   

Hate Allen screws, just seem so out of place on our machines.  That said, I do have one holding on the dynamo cover.  Will replace as soon as I find a suitable fastener (is this Fillister too?).

My dynamo cover is held on by a small cheesehead screw. I reckon that is probably correct.

 Allen's make life easier, but they do stick out on old bikes.

 I really dislike how they always collect water, first thing on a chrome bike to rust (and gall).

Not really keen on Philips screws either, especially the 'combined' slotted/Philips.  I must admit, that I do have a few of these on the bike too (cutout and horn/dip beam switches plus rear light lens screws), but I'm always looking for 'period' replacements without spending too much time on it.  Sorry coater87, just can't abide Allen's on vintage machines - seems wrong somehow. 

Need to be careful, going off topic
