Happy [insert preferred commemoration here] & thanks gents,
& thanks too for the clarification Robert Jan, I guess RJGSvM could take longer to type! The opposite irritation to my own, often being called by surname because it looks like a first name…talking of which hi Maarten, I can’t recall where you first posted that one but I know it was pretty special so I’m honoured to accept it on behalf of all the contributors to this project.
Back at the workbench, indecision set in about whether to make the roof or the ceiling first – obviously they’re inter-dependent & I’m still hoping for images of 624’s interior. So eventually I opted for the latter because without the roof in place I had unimpeded access to the panels from above & below…

Then I tried dry-fitting the original kit bulkhead in place, just to see how it looked from the outside…

Invisible eh? Revealing…or not, it’s close to replicating the view of Frenchy’s image posted April 12th . Not so hard to see from these angles although if I’d put in all the window glass…

..so I’m inclined to believe the trailer did have bulkheads after all - I’ll convert the kit parts to fit but allow some more time for interior images to fall out the sky. Moving on, ceiling panels completed…

No detail on the ceiling panels yet apart from a “spine” bar to support the lights and, presumably, the three air-vents…

Talking of which…

The spares boxes weren’t helpful with the cones, so I used a school pencil-sharpener on a solid rod of styrene to make them. The base mountings were originally for a Panther G rear deck (I think) & the brass rings saved me from the difficulties of cutting plastic versions…

The ventilators aren’t glued down yet because I’ll need to lay the roof on its back for ceiling work. Sure enough these photos don’t look as good as through the rose-tinted optivisor, and the un-remediable howler in the undercarriage drives me nuts every time, so the above view will probably be the last time you see the trailer from this side…
