Just a note that I recently sold all the Japanese models shown here (excepting the ED29) to a keen and very Japanese knowledgeable local modeller, they have gone to a very good home.
Sankei's Warehouse kit has been built as per instructions however with the roof scored to add some 3d profile, and the roof ridgeline, main walls, door and stonework painted before weathering of all surfaces and dull-coting. A visible brush style was deliberately used on the main building body (cream) to simulate an older, hand applied plaster look. Paints used were Vallejo and Tamiya, all acrylics.
Endo PRUS kit was built up per instructions but with side protection bars and brake steps formed up from styrene strip, wire brake handrails and brake hoses as shown in the pre-painting picture at base above. I did'nt replace the moulded end handrails and coupling levers as they aren't overly visible in use. Again these kits have rub-on decals which were applied this time prior to assembly - much easier than after! As an experiment I didn't spray paint these wagons black, rather used the base plastic colour and just painted the interior and details, before weathering and dullcoting.
http://www.jnsforum.com/community/) I fitted Steam Era Models 10.5mm dia. 23.8mm axle wheelsets, choosing Code 88 for the finer appearance. I have used Steam Era Models (http://www.steameramodels.com/) products for much of my other modelling and their wheelsets are both very accurate and very true, these are no exception and I will be using them for all subsequent stock where appropriate. The underframe detailing on these kits really surprised me given I understnd this to be an old kit. For new modellers, the decals work best if soaked in hot water - I wasted quite a few before I realised this. The wagons were spray painted gloss black before decalling, with the brake angle and step support being picked out in white, before weathering and dullcoting.
