The wonderfully retro Chiver's instructions (possibly done on a Amstrad PCW?) say 'to allow a finescale model to be made, the mainframes have been etched with limited clearance'. I removed these half etched sections with a file - which proves once and for all that I'm not a finescale modeller.

In fact I had to remove a little bit more (and elongate the bogie pivot hole) to get the chassis through a B6 point. The extra clearance was needed to clear the flanges of the Gibson wheels - these are to OO finescale standards, and although a little oversized are nowhere near the great pizza cutters that were on offer from Jackson/Romford etc back in the 1980s when this kit came out. I suspect you have serious problems if you used coarse scale wheels on this kit.

And some more work on the body - the boiler is still only resting in place, but has gained some fittings. The done required a little bit of fettling to get it to fit, which is possibly the only real difficulty I've had with the body castings for far.

Slightly blurry at the front end, but you should be able to spot the Keen-Maygib SECR pattern buffers which I've substituted for the cast ones supplied. Very nice cast ones, but I wanted sprung buffers.

Apart from the problems with the chassis, this is turning in to a far more straightforward build than I expected.
