GROUP: Lost & Found Property on Greater Anglia

AUTHOR: James Sparks

Total long shot, but three days ago (July 4th) I left a Canon AE-1 Program on an afternoon train from Stratford to Bishops Stortford.
I got on at Harlow Town station. It’s pretty distinct, with a large zoom lens and a blue, red and white sticker decal along the side.
This camera originally belonged to my grandfather, so it has great sentimental value.
If anyone has seen anything, it would be a great help!
Thanks:)
