40844+40845 have been applied to the two Optare DDs of the expanding midland bus company Diamond, acquired with the Johnsons bus business, which reminds me of -- --
4844+4845 -- a pair of DDs acquired by the still (slightly) expanding Midland Red, along with the Kemp&Shaw business in the 1950s.
Also, First Midland Red has just acquired two vehicles with the fleet numbers
44943+44944, which reminds me of the famous pair of Midland Red D10s --
4943+4944.
I can think of a (most excellent) chap at the Transport Museum, Wythall, who might have noticed the latter numbers !! -- -- -- anyone else ??
