I was looking through 'British Railway Wagons - their loads and loadings Vol 1' by Brian Grant & Bill Taylor and on page 115 there is a picture of a 'gunset' wagon for the carriage of large gun barrels which i have never seen or heard of before,these had 16 wheel bogies compared to the 'boiler set' which had 12 wheel bogies, my question is, i presume they would have been built for WW2 and the info says that only one remained by 1964, so there must be more pictures of them if they were around for 20yrs or more but web searches have drawn a blank so i'd be grateful if anyone has any info,pics or drawings as i'd like to scratch build one of these oddities one day.
