Gentlemen, thank you for your replies. One in particular jogged a long forgotten memory that somewhere in the distant past, Lasham was mentioned.

I did have a letter published in the Nottingham Evening Post about 15 years ago in the hope some one might know what happened to it (the L.5) but there were no replies. From the serial lists kindly posted I deduce that the serial on the photo is made up from the (4)2 99015 and that indeed this one has slipped though somehow.

I have found that in other areas of research there can always be errors in published data.

This is the only other pic I have.

Cheers

John
