Hi Merf
No further progress on mine yet..... work getting in the way.
As you've probably read on rmweb, the buffet cars are extremely hard to get apart, because the windows and the roof are moulded together, as one piece.
Also, the bottom part of the window moulding jams against the seats internally.
I tried the various suggestions on rmweb, and none of them worked.
In the end, I used an fine, Xacto saw, carefully make a cut between the roof and body joint, the whole length of one side of the coach.
I found that this enabled me, with a fare bit of wrangling, to get everything apart.
Another suggestion I saw, which is worth a try, is to slit the intercoach doors. This is supposed to allow the sides of the coach to be eased apart,
to release the window mouldings from the wedge between coach side and the seats.
A made a complete mess of the buffet coach, with my varnish disaster, so I have another on order..... think I'll try slitting the doors on this one.
Best of luck.
