Model A - headlamp supports

 Well I guess you have to start somewhere. Looking around the bike I realised that the headlamp supports - which are just bits of flat bar - weren't fitted correctly, and one of them was very bent. 

Take a look:

The other side was upside down as well, but not as bent as this. This is how it is supposed to fit:

Here it is again, after I have done most of the straightening work on the headlamp bowl. The riveted mounts on either side are now in the correct place and I have straightened the nearside lower headlamp mounting bar.

It's still not sitting centrally though - the headlamp mounting bars don't match: the near side is more straight than the offside pushing the shell towards the offside. I will have to look at some pictures and try again.
