Whereabouts of 611 and 1218 Excursion Service Auxilliary Tenders

[nw-mailing-list at nwhs.org]

I want to model the Auxilliary Tenders that the 611 and 1218 during
their days in Excursion Service.  Ideally, I'd like to know where these
A-Tanks are located so I can measure and photograph them.  But if
they're not available for inspection, I'll settle for drawings,
diagrams, etc.

Any help would be appreciated.
