O gauge Tunny and Grampus kit builds

With the layout packed up for Xmas I have made a little progress on finishing off some wagon builds. The couple I have been working on are two engineering wagons, being a Grampus and Tunny. The Grampus wagon is the standard Peco (Parkside) kit, built as per the instructions, which I finished off a few weeks ago. This is a simple kit to build - the parts go together cleanly and the end result really looks the part.

The second kit to finish building was a GWR Tunny wagon. This is a 3D printed kit from Skog. Compared to the Parkside kit, there was a lot of cleaning up to do of the printed parts, not least trying to remove the print lines, particularly from the exterior of the wagon. The wagon was built with a lot of spare parts from other kits; the brake levers are the spare set from the Grampus build and the axle boxes are Slaters spares. However, overall it is has built up into a good representation of the prototype and I am sure will look great once painted. The kit will need a thorough scrub when it gets cleaned later today before heading into the paint boxes.

The sides took a lot of filing down to get rid of the 3D printed lines.

The close ups are probably a little bit cruel when it comes to the Tunny wagon. However, with a good wash later today and a decent paint job I am certain it will look the part. Whilst the Tunny kit was a bit more basic than the Grampus waggon, it was also under half its price. It therefore represents excellent value for money - although I would definitely recommend having a cache of spares available to help detail the kit.

With Xmas fast approaching I am limited to a bit of modelling on the kitchen table alongside doing a bit of painting. The next wagon build has already been started - a Slaters SR BY wagon, again to be finished in BR engineers olive green. I also have severeal buildings to finish off for the layout, alongside completing the painting of severeal wagon. So there is plenty to keep me busy over the next few weeks, whilst the layout is packed away.
