The loco is now back home, having been collected at Scalefour Crewe on Saturday. It has been painted, lined and weathered by my friend David Clarke, based on a photo of a sister loco taken at Lees Shed, Oldham, in the mid 1950s.
Jobs still to do include the large diameter buffer heads, cab glazing, inserting the cab inside detail and adding some real coal to the moulded version in the bunker.

The 18" buffer heads, described earlier, have been fitted. I suppose that I should really change the BR Standard buffers to be the same.
The cab interior has been temporarily fitted and real coal added on top of the plastic moulding.
I had hoped to cut down the Bachmann glazing inserts and re-use. However, the side windows are rippled and for the spectacles, there are three LH and only one RH. Not sure how the factory managed to fit them. Anyway, it means new windows will have to be cut from suitable sheet material with the attendant difficulty of getting a good, tight fit in the openings. Grrrr.

No problem, Tony. Shots of good looking models are always welcome.
The Bachmann body is very accurate, dimensionally, if somewhat lacking and crude in some details. I built a BR Standard version of the 4 mm DJH kit and found the cab to be too short, particularly the width of the door opening. My solution was to split the etch and stretch to door to make the cab length correct. This did mean the door opening is now too wide rather than narrow and a replacement roof was required.
Thanks Dave, yes I'll be using canopy glue but still have to get the windows something like to hold in place whilst the glue sets. With etched cabs, I usually cheat by simply fixing the glazing to the inside surface, so the actual size and shape isn't too critical but that's not possible here.

I've managed to make and fit the side windows and front spectacles, on both sides, without too much problem, as seen below. However, for whatever reason I just don't seem able to get the size and shape of the rear spectacles quite right. I've had a go at four so far and none quite right, so there's a (hopefully) temporary loss of enthusiasm.
At present, the windows have been attached using Humbrol Clearfix canopy glue, applied round the openings before inserting the glazing. I'm wondering if it might be a good idea to try to run a fillet of diluted Micro Kristal Klear round the inside to reinforce the joints.

I glued the end windows for my Wickham DMU in with Micro Kristal Klear and it seems to be holding up OK.

That would be one way round. That said, not a single photo of these locos working on the branch show the spectacle plate windows open - in an area where it reputedly rain 366 days a year and summer doesn't arrive till the end of September and winter starts in August, even an enclosed cab wasn't too oppressive.
Anyway, that consideration isn't necessary because I managed to make two rear spectacle windows to an acceptable shape and these are now secured in place.
All the window joints have been reinforced by applying a pool of Mikro Kristal Klear to the inside and then mopping up the excess using a dry brush and capillary action. Just waiting for it to fully dry now.

A bit too weathered for my taste, but excellent non the less. An error I've made on mine that you have got correct, is the oil feed pipes on the outer face of the lubricators. Only the left hand one has them but I put them on the right side as well. Easy to correct though.
Cheers,
Peter

Thanks for the comments.
Larry, I wholeheartedly agree about the Bachmann update. The original body moulding is quite accurate but the level and crispness of detail is far below modern RTR standards and would surely have warranted a retooling upgrade. There again, this project started long before Bachmann upgraded the chassis, so I'd probably been stuck with old body anyway.
Yes Peter, it is quite heavily weathered but is based on an actual loco at Lees shed, 41282's home depot, in 1955 - bang in my period.
The LH lubricator served the cylinders with very gooey cylinder oil, so was provided with a steam heating coil fed from the atomiser steam supply, and that's the extra low level pipe visible across the front of the lubricator, below the oil feeds. The condensate outlet is on the other side but is less visible. On the push-pull fitted locos (and a few others) the LH lubricator was a different type from normal, having a bolted rather than hinged top cover, with a screwed filling spout near the front. The vacuum diaphragm unit would prevent opening of a hinged lid.

Larry the difference is that Bachmann never did the 2-6-0 before, so it was a new tool in a newer age than the tank had been designed in. It made sense to allow for the new chassis as the split axle ones had a habit of breaking their muffs. As Dave says the fundamental dimensions of the Bachmann tank are good so certainly worthy of a polish! I love the finish - dirty but showing signs of someone trying to clean it occasionally.
Hornby did a caricature of the 2-6-0 in the past.

Love to visit again, Andrew. I don't suppose you're at Wells again, this year?
One of the lovely, but extremely fragile (horrendous attrition rate on the loop handles) Modelu lamps has been fitted, using Blutac in the built-in hole, to the top lamp iron to denote a stopping passenger train.
