You know what it’s like, you look through some old family pictures and you come across some where you don’t recognise the people, the location is unfamiliar, and the occasion is a mystery.
It’s the same for us. Sometimes the original information with the photos is lost, or we have been sent them in the hope that someone, somewhere, can solve the riddle or come up with some information.
Our readers are always the best detectives, so examine the evidence in these images and see if you can spot any clues that might help put the pieces of the puzzle together. Let us know what you discover in the comments.
And no, this isn’t some sort of test where we give the answers at the end. We really don’t know.

1. Miles of smiles
All smiles from this charming group of young girls. The picture was in our old Bridgnorth office, so they are likely to be from that area, and that looks like a gym floor. Recognise anybody? | Bridgnorth Journal

2. Grassed up
This was found on a grass verge by the roadside in the Battlefield area of Shrewsbury, happily sealed in a polythene bag which meant that it had not suffered from the ravages of the weather. It is a professionally taken photo, and handwritten on the back is: "21st birthday party, April 7th, 1951." Our best guess at the photographer's stamp, which is very faint, is "C & F McKean, Photographers, 13 Bridge Street." Those are your clues. Who are they? Whose birthday is it? How did the photo end up on a grass verge? | Unknown

3. Rare bus
"Jim Robinson (left) and William Robinson, outside the Six Bells, Bishop's Castle." That much we know. Your mission, if you choose to accept it, is to identify the bus. One theory is that it was one of only five built specially for airport use. The picture came from the late Mrs Joan Robinson. | Joan Robinson

4. The Italian connection
An unknown event in Bishop's Castle which seems to have had an Italian connection. The name Mainardi (which is a common Italian name) is readable on the ribbon. It is outside St John the Baptist Church, and that looks like a bier in the foreground. Without a coffin. And they don't look dressed for a funeral anyway, so this might be a commemoration of some sort. | Unknown
