Past Present and in Between in Pictures (Part 1)

TIDDERSON:

Ray Smyth:
Thanks to Gerald, Pete, and Robert for your comments on the BRS Austin artics.
They were fitted with Scammell couplings, probably part of the BRS Parcels fleet.
I imagine they were painted in BRS Parcels “Green”.
Cheers, Ray.

The 2 that I can identify are Austin 5EFED units rated at 8 Tons. They were new in October 1956 at High Wycombe depot and painted red. 823 AWL and 824 AWL. Later fleet no.s were 4G311 and 312 Later transfered to Swindon

Is that a Maudsley in the background? Whether or not, what engines did they use. Anyone know or remember?
