Thank you for this information... given the dates the model will fit quite nicely with S7 models of Cl.37/4. Just how long is the queue waiting on news of availability?

I don't think the queue's that long, but I'm not sure if I am going to make them available yet though. It will depend upon costs, order quantities of castings and deciding whether I want the hassle or not, I guess.

On my layout there'd be a couple of them, tripped in behind a Dapol 08........ outweighed by the satisfaction of seeing them on more O scale layouts coupled to Class 33s....
oh
starting to sound like a wishlist....

They're way out of my preferred era, but I'd buy some too!
Keep up the good work Pugs.

Thanks for the kind words everyone - I'll let you know if they do become available.

It's been a while since the latest update, due to a lack of time, and redoing parts after schoolboy errors. In the virtual world, it currently looks like this:
I used the specification sheet I have for these vans to determine the amount of gap to leave between the two doors, in the middle of the wagon, which was 300mm. I then spent ages working out and drawing up the 4 layers that comprise each door, before looking at a photo and realising that something was wrong.
The support may be 300mm wide behind the doors, but the visible part is only as wide as the narrow ribs on the doors, approximately 80mm. It seems to have taken longer to alter everything than it did to create it in the first place! The moral of this story is to study your photographs carefully, not rely on published dimensions that aren't always clear.
Heljan, take note

Good evening all - please can you tell me what's wrong with my roof. There's something I don't like about it, but can't figure it out.

Any help and observations would be much appreciated.

Possibly... although the operating gear on the end of the body looks like there might be a gearbox at the very top with a longitudinal rod under the central portion of the roof. I meant to say in my previous post that the central roof portion seems to have different widths / cross-section on different wagons (see reference to Paul Bartlett photos).

Another guess - is it a central 'spine' that houses the top rollers for the sides, which open by moving out and over each other..? As shown in This Picture.
Comparing the photo Pugs has linked to, I'd say it's not the roof that's wrong, it's the sides, which don't overhang the end enough. There's quite a deep shadow under the roof/side end on the prototype which isn't on the drawing, leading to Graham's comment about the cross-section looking too deep.

May I suggest using a bit of photo-software-trickery?
Take an image of a prototype where the end is visible... import into photoshop and select the distortion option. Grab a corner of the prototype and move around so as to get the end in a psuedo end-on view... then see if the image is good enough to "trace" the section of the roof relative to the corss-section of the end.
Clearly there is a need, for purposes of accuracy and comparison, to select a prototype image which has the roof style which is required for the model.
Irrespective of what has been written before, thank you Martin for treading this path and showing all of us just what can be achieved with current computer software and associated technology.

Some of the ones in Paul's gallery are the later type, which are both higher and wider, and also have a different roof arrangement. Both of the later diagrams seem pretty similar, but the first 100 were different.
As Jordan mentions, various gubbins related to the operation of the doors lives up there. The operating gear on the ends is the unlocking mechanism - AFAIK the doors are moved by hand (or mostly by fork, by those too lazy to get off their forklifts, probably).
Jordan - I've manged to orient the model closer to one of Paul's photos - I think the overhang of the ends and doors is about right comparing the two. Have a look and see what you think.
I'm also forming the opinion that the roof sheet is in the right place, but what's wrong is the angle of the door tops - it should be flatter than it is. This would increase the gap between the roof sheet and the doors, and improve the appearance.
Again, any observations welcomed:

Looking at all of these pictures has also made me think that I need to revisit the buffers, there' not quite the same type as on these wagons. Still, better to notice something now than after everything's been cast!

I wonder if the roof angle problem might be better addressed in proper 3D rather than virtual 3D and that it's time to make a simple paper or card box to the dimensions of the computer model? I've found it quite difficult comparing when clicking from image to image and though printing them out would help it's better I find to have a mock up that can be picked up, rotated, tilted and viewed from all the angles one would want to. I suspect that only using the PC to design might be like only using whitemetal to produce a loco kit.

The recess will be half etched, for some reason Alibre won't display half cuts on the model. You're right about the fillet though, I need to amend that, and I think you're right about the door angle - that's the bit that's not quite correct.
I think that's a good idea - I'll give that a go over the next few days, not tonight though, I fancy a spot of weathering instead.
