[4firstimes]

I am seeking information on the following Three EM gauge layouts by D. Mundy who delveloped the Sprat and Winkle Couplings from which his layouts showcased this coupling System .Any modeller who an help with the articles or provide information so I can obtain copies of the Magazine. 
The first layout is Somborne which was a double track through station based in southern practice . I think the article was in three parts in either the former Model Railway Constructor or the Railway modeller .This layout , Derrick replaced with “The Sprat and Winke Line as was seen at York 1978/79 , reference in the show guide indicated an article had appeared in on of the magazine.

The following York Easter show or Central Hall Westminster there was a layout called Somborne based on a LSWR location as end to end in around 16 ft had replaced his sprat and winkle line. 

I Would like to obtain copies of the articles from all three layouts

 

kind regards for any help
