I usually work of photographs, as we do, and the van I worked off had no tiebar between the W irons. As for lamp brackets, I don't know when these started to be fitted, but they were not in place on many vans in the 1950's. One might assume they were fitted when goods trains no longer required a brakevan (in the 1980's ?), but of course they must have had lamp irons long before then so that vans could be hung on the end of passenger trains. I made a strip of lamp iron in plastic and cut them off as required, so they are not a problem.
Vans like that GW one - often built unfitted - were retro-fitted by BR with vacuum brake during the '50s. David Larkin has written about this extensively as has Don Rowland and others. The spec' invariably included a tie bar where one had not been fitted - I can't see any in Paul Bartlett's gallery that lacks one, for example: GWR Vans - includes specialist designs - usually extended buffers (with with collars or replacement OLEO or other hydraulic types), screw or instanter couplings and a lamp iron. The latter were fairly inconspicuous - the one here is only visible because it was painted white: GWR Vans - includes specialist designs | 041886 [ADW65643] GWR ply van @ Long Marston 92-04-15 � Paul Bartlett [3w] and that was far from typical (I've not seen one so-treated and I've looked) in the '50s.
Here's a typical example: 25/06/1963 - Hessle, East Riding of Yorkshire.
Note the forged instanter (round in section), tiebar from strip (the GW preferred rod) the low level vac' pipes and the replacement plate front axleboxes. I make my tiebars from brass angle (0.8mm is scale, but 1mm is near enough - the angle faces inward and adds rigidity and surface area for glue fixing) but have used strip.
