I'd been promising myself this kit for some time now because of it being something slightly different and away from the mainstream 7mm kits available, so this morning it arrived safely and well packaged from Taff Vale Models who are based in the Vale of Glamorgan. Now on opening the box I was nicely suprised with what I found inside, well documented instructions with colour step by step pictures, etches neatly wrapped in multiple layers of tissue, the white metal cast parts separated into various sealed bags and stapled onto a stiff card backer and finally the different wire lengths all tied together with a foam end block to prevent distortion. Nice, these are all the hall marks of a good kit because I always measure the strength of buildability from the standard of presentation in the visuals, the instructions are laid out in chronological order too giving a list of parts, historical info and most importantly the wheel size needed with the code spec, gearing motor and couplings are left for the builder to source for themselves. The North Staffordshire Railway M Class was an 0-4-4 passenger tank engine built in two batches by John Adams for use on the tightly curved Potteries Loop line where the curvature into Hanley station had a C1 restriction, M Class loco's also ran up the Cauldon Line to Waterhouses on passenger workings from Leek. Later M Class locos had longer bunkers and were designated New M, etches are provided to make both versions. So enough of my ramblings and as Toto will say ... lets have pic's of the shiny stuff. First off the contents as placed in the box and instructions. Next off are the white metal castings which include Midland pattern buffers all pre assembled so tiny parts don't go missing, the backhead casting, chimney and dome are all very crisply formed with absolutely no distortion at all, also included are a few lost wax castings such as safety valves and whistle. The main frames and other associate items are etched in 28 thou nickel silver, this is going to make one very solid little tank engine. The etch brass parts are 18 thou and have a good crisp definition, the boiler and round top firebox is pre rolled so that helps too. Note on the top fret you will see the two different bunker sizes provided depending on which version you want to build. Tiny half etch bunker and tank rivet detail is provided so the builder will need a fine point press and anvil (4mm OO scale) fitted to their rivet embossing tool. Another thoughtful touch is the fret containing smaller etch items has a legible numbering system incorporated so identification is made simple... that's another nice touch showing the good level of care and consideration taken by the designer in his product. Finally how much... well for £265 plus P&P this is very competitively priced by Taff Vale Models and aimed particularly for the steam enthusiast who will want such an attractive little locomotive in their collection, I can see this one being a talking point amongst visitors on Dundee's Another Bridge, Toto's Luib Bridge and my own Ashbourne Line Norbury Bridge (when I get round to building that one). Pragmatically speaking I shall get the wheels ordered first before cracking this kit open and fit a 38 : 1 gear with 1833 motor with sprung pick ups. So all in all since this is my first Taff Vale purchase this kit gives me a good feeling of confidence and I am looking forward to the making, you never know I may quite easily be tempted into buying another M Class so I can do the earlier 1907 version as well.
