You don't want it like this then Steve?
It may also help the person that wanted to get the smokebox door as well.
I've had a look at the photos of the front ends of the A4s and some of them show what we all know as rivets, some of them may be rivets and some of them could be coach bolts that have nuts on the inside. As most of the plates would have been needed to be removed on shed. Like the front plate that has the number on it in the above photo, so that the shed staff could get to the inside cylinder and piston valves.
In some of the later photos the round headed "bolts" have now changed to flat headed bolts. It was cheaper for the works to do it that way in the later years. As these could just be bought off the shelf.
Some of the "bolt" fitting could have been to do with new fixing under the sheet metal, with the rivets from the old days removed.
This photo is also interesting in showing three types of front end lining on the front end of the A4s, it looks like only one is about the same as the one in the bottom photo.
If the above loco was painted in Doncaster it should be correct. The placement of the electrification flashes could be in any position on the E./R.
Canadian is one of the last locos that was painted by any of the B.R. steam paint shops, yes I know this loco was painted at Crewe but the two works did talk to each other. It would not surprise me if some of the Doncaster paint-shop workers came over to do some of the work (not proven).
OzzyO.
