... Vee Hi John, Pre-grouping designs usually had a conventional chair casting with keys for the "A" timber. The bolted slab& bracket designs were introduced after the grouping, but the earlier designs would have lasted well into the 1950s in places, and there may still be a few around. Here's a couple of slab& bracket pictures: 1. GWR design, plain bracket castings, the slab has square corners and an angled section for the holding-down bolt through a pojection on the vee point rail: 2_121258_410000000.jpg 2. BR design, ribbed brackets, rectangular slab with radiused corners, no holding-down bolt, extra nose spacer blocks instead: 2_202055_480000000.png In both pics you can see the spacer blocks between the wing rails, but they don't fill the entire space. A fully filled space looks worse in models because of the wider flangeway gaps. Of course, the white pre-production pics make it look even worse. cheers, Martin. posted: 30 Nov 2018 22:57 from: Rob Manchester Martin Wynne wrote: ...
