Help needed please : Can anyone identify these MK1 coaches please?

[Blobrick]

I found this photo on the Rail online web site. Hopefully l ve not been too naughty by cropping a section of the relevant subject in the photo. It shows a BR class 21 just arriving at Larbert, some time in the 1960s. The train consists of three Mk1 coaches, which is made up of a Brake bringing up the rear and what l suspect are two SO/SF coaches. Can any of the experts amongst the Rmweb membership identify the vehicles in question please?

 

Thanks in advance

I think the first coach is a composite as it only has 7 compartments. Second coach is either a corridor or open second.

Agreed, the nearest is definitely a Composite Corridor (CK) - four First Class compartments nearest (with the '1' visible on the nearest door), and the middle window of the Second Class end has the inward-opening window for stretcher loading.

 

The middle coach is all Second Class and the number of roof vents indicates a Second Corridor (SK).

 

The spacing of the four windows of the furthest vehicle makes it a Brake Second Corridor (BSK).

 

So all compartment stock on this working then - ah, those were the days............fondly remembered (sigh).🥴
