Preston - September 1967.
Although I have put the date as September 1967 I have been unable to find a precise date, it possibly could have been late August.
The 3 recordings are:
A) 44767 with a northbound freight (despite what I say on the recording!). This is of course the unique Black 5, the only one with outside Stephenson link motion out of a class total of 842. I don't know if it is possible to tell from this recording if 44767 has a unique sound or not - does anybody know the answer?
B) In 1967 I still thought that the very first Black 5 built was this one - 45000. No doubt reinforced by the fact that 45000 was to be preserved as part of the national collection. I learnt years later that the first Black 5 was actually 45020.
C) 45444 passes though Preston on a freight.
