Yes I remember that article/letter too! As above I know 92240/73082 & 34059 all got complete tender frames in one shape or another, additionally as pictured above any chassis was missing its centre wheels so another frame donated wheelsets to these underframes. I recall the Bluebell selling a set of Bulleid tender Boxpox wheels to the Southern Locomotives Ltd team that had the axle chopped in half, also I think 73156 has some bits from a recovered frames from Briton Ferry. Not sure about 73096'd tender being ex steelworks as I am certain it was a LMS Jubilee 45593 Kolhpour tender at withdrawal/preservation who then purchased Alberta's tender from a scrapyard and sold it years later for use with 73096. Anyways none of this is about 35011, so apologies and back on topic.
