The mother-in-law has just gone through the process of scanning many of her late Father's old snaps. He was a sailor in the RN from the age of 16, lying about his age at the outbreak of WW2. She doesn't have his service record (yet - I'm helping her get that from archives) but believes that this photo was of one of his ships. I wondered if anyone here might be able to identify the boat, despite only showing part of its (pennant?) number. I'm guessing it is an escort destroyer of some sort, but I don't know the class. Many thanks.
