Nominative determinism in action? Plenty of interesting items in the programme, so I'm also looking forward to this show.

Re: LMS or BR

Do I detect an LMS design 'No smoking' target on the right hand quarterlight of the nearest compartment in the Period II BT shown in the 1952 photograph at Edington? The second straw line above the windows is almost completely indistinct. I think the number for this vehicle can be seen between compa...

If you have a copy of the Wild Swan profile on Midland 1833 and 2228 class bogie tanks you can find a drawing that shows the brake release spring arrangement as applied to the nearside leading hanger at page 32 (I can let you have a copy if you don't have this profile).

Re: Johnson 1P

Those look like very neat jobs both on the brake cylinder and the smokebox door - I can't detect where you changed the locking dog positions. Smokebox door handrail positions could be a moving feast: on 58086 the rail was above the top hinge on arrival on the Dorset, but was subseqeuently reposition...

Re: Johnson 1P

Looking good, Dave! I recommend you to profit from my error and substitute a more accurate smokebox door in the place of the one supplied by Craftsman, which is too deeply dished and oversize in diameter. If there was one thing I could now change on my model of 58047 it would be this, but too late d...

The photographic record provided by Messrs Peters and Lockett suggests that from around 1950 Bath's allocation of Ivatt 2-6-2Ts supplanted other forms of motive power on most of the Bath-Bristol via Mangotsfield passenger workings. The S&D' s Evercreech Jc-Burnham-on-Sea Branch was one of the la...

Re: A few things on my workbench

I've always had rather a soft spot for Bloaters, perhaps because the sliding door configuration was a quite an uncommon feature in GWR wagon design practice. Only managed to see one 'in the flesh'; this was an example that infested the S&T Works yard at Reading for everal years in the late 1960s...

Re: Future Project?

For some reason I'd got it into my head that the inside cylinder on a Scot was offset from the centre line but the GA reproduced in Nock's monograph shows that I was wrong.

An interesting exercise - look forward to hearing how you get on!

I expect you've come across the photographs at http://sutherland.davenportstation.org.uk/aaprint/ash.html . The picture 'ash-64-04' is helpful as it shows quarry traffic being shunted, with what looks like an ex-LNW tender outside the brake - probably in use as a water carrier. 'ash-62-15' shows the...
