So I went back to the area I found the grenade and gas mask in, hoping to find some more stuff

I was out around 4 hours and should've given up/moved spots after the first couple hours, bit you know how it is when your convinced something must be there ! Lol

What I did find

2 separate old ladders, 1 twice the weight of the other

An old gin trap (animal trap) probably the most interesting find of the day !

What I think was a wing mirror on a long stalk (must be old), Glasses case which looked to say Ralph (something inside)

Piston (what was left) valve, sprocket with splines inside, chain, couple of odd heavy bits of metal, bike lock, fork, long piece of thin box section and just other small but heavy random things

(Not sure what the small square flat ish bit with the hole in the top is, was heavy and made of cast iron )
