Thanks, Garry, but one would have thought that they could have come up with something a bit more technical than a cork!
On the GWR... a cork with a piece of split cane down the centre of the cork. The cane was to allow the oil reservoir to "breath" as (a) oil was used and (b) the air in the reservoir expanded (thereby stopping the cork from being blown out of the aperture and oil forced into the bearing).I think you would be hard pressed to find an alternate material that would do the job as well as a cork does.
Jon, Nick Dunhill's build of a pair of "02's" (a close relative of the G6) might be of interest? 257 originally had a longitudinal rainstrip (as in the photo you posted earlier) which was replaced by 1922 by the more familiar transverse central stiffener and what I take to be a gutter or downstand around the roof. I've one or two photos (which I'll pm to you) which suggests to me that 257 might've had the handrail added in Southern days..I've also noticed that on the roof of 257, there is no downstand around the edge of the roof but there is a drip rail(?) fixed onto the roof just above the cab openings. Some drawings show an handrail on the outside of the rear wall of the cab. The drawing that I have shows this but it also shows the roof having a downstand. I wonder if 257 has the handrail though, Mmm.

GaryHave a look at this, may help.
I did find that on the internet and copied it down. The problem is that I haven’t a clue how to decipher it.
