My grandad recently passed away he was in the 52nd lowland division in signals we found German maps rather alot of them I don’t know if they are worth anything or whether they will just hold centimental value I am not looking at selling them but I dont know if they had a particular value to themI have alot of photos of Germany during and after that I am going to upload soon so if anybody can help with those aswell that’s old be grateful
He was in the 52nd in the war but stayed on after the war with 1st corp signals but he used to tel, us small bits while in the war but never to much and mentioned nothing about after the war.We have found a couple of things out after the war he was based in iserjohn please excuse the spelling were he also started up a band in the lagoon bar but that’s as much as we know His name was Leslie Marriott If anybody knows any more info it would be fantastic to find out more
