I made a cement hopper out of what I thought was a shampoo bottle top that I found, then I find another one today (outside on the pavement)
I wonder what they are, maybe it’s from a kids toy or something. It’s a bit coincidental to find two in totality different locations over the past couple of weeks. 
Anyway, I feel a coal hopper coming on. Just the right scale for N. 

Certainly looks like a bottle top Gray

Hi Ed, I’m intrigued as to what it could be. I think I’ll be scouting round the toiletries aisle in Tesco this weekend.
