Not the best of pictures taken with box camera in my early days of spotting. The eventually preserved Royal Scot 46115 Scots Guardsman (9A) and EE type 4 D377 (5A) were a triple-headed light engine movement. The other engine was filthy so I thought the Scot looked the better one to take a photo of. In my ignorance at the time I didn't think the number of the other engine - 46208 - particularly significant! It turned out to be the only Princess I ever saw in active BR use and I missed the chance to photograph it. The EE Type 4 was in the middle and the engines were travelling from right to left across the picture. The Princess was Liverpool Edge Hill based and named Princess Helena Victoria. I did see 46201 and 46203 during 1963 - but both were in store
