My old Triang model had already been bashed to Sentinel D89, pretty accurately dimensionally, using lots of odd bits from other kits or models, but with only the louvre doors and driving cab windows needing starting from scratch...
I do not know what it was originally as the paintstripped superstructure is 25+ bits of plastic pacthed together.
But the paint job was really poor, the styrene strip for the panels and windows way overscale, and there was lots of glue on the glazing, so it needed stripped back to basics with that one for the rebuild.
I'm more than happy to restore this as a project, and should have only mentioned it in passing as I was more wondering how I might complete one of the 3d printed shells for a second railcar and this was what I was finding the challenge. Aye, my original post doesn't make this clear !
I have got a copy of of the Isinglass dwgs, (eyp.. 4/280) which is very helpful, for Dia 97/96, but what type were the bogies marked as 6'6" and 7' on the dwg ?. Other underframe bits are identifiably from the Isinglass dwg.
Did Sentinel use one of the Fox variants, or some other type ?
This is where my ignorance of the technical details really kicks in..
These shells have been noted in another thread as being very expensive, but the increasing price and scarcity of Nu cast kits on Ebay makes building from a shell look like a much more reasonable value for money option.
There's a classic pic of a Sentinel crossing Durham viaduct which was one of the inspirations for me to get into LNER modelling, and both they and push-pull autocars have become special interests. Dunno quite why...
The pushpulls are equally complex ..but that is quite another story !
