(Some of us still have to work for a living on Bank Holidays.)
Naturally I armed him with a list of things I needed pictures of during his visit to Boston Lodge Works.
The first thing reported back to me - which will come as no great surprise to readers of this blog - is that the second of the Super Barn observation cars, to be numbered 152, will not be an identical twin of the first.
152, or at least the steel skeleton, was transferred from Dinas a few weeks ago and the carriage works team are already working their magic with wood.
The breaking news, for me at least, is that 152 will be different at the front to 150.
Instead of one single pillar at the front of the observation saloon it will have two either side of the centre, making it look a bit more like the WHR Pullman 'Glaslyn' perhaps.
More frustratingly there is another very subtle change at the front.
Unlike 150 which was flat across the centre above the drawbar, 152 is being built with a very slight curve, as you can see in the picture below.
This means that I will certainly have to create a new master for casting the front section of 152 when I come to build it - and this piece was one of the most challenging aspects of doing 150, so as you can imagine I am delighted about that!
I now have my fingers crossed that the sides will be a match for the first carriage so I can at least re-use those parts.
It is probably a forlorn hope.
