Still not sure about details for the photo yet but I will post what I can get when I can speak to the chap who gave it to me.
I never thought that the object to the right was an entrance, I just assumed it was a shed of some kind ! I'm no expert on this, and I agree that this lady is far from a pit brow lass as I'm from Wigan and have seen many a photo of pit brow lasses to last me a lifetime in this neck of the woods !
It's a pity the buckets are empty, but the fact that most of them have a bucket and a couple seem to have long scythe or hook type things leads me to think that whatever they are doing it's small scale.
I had also noticed that our tall friend 2nd from the left also has a similar small metal container strapped to his belt, and it looks like the one the chap has squatting with a bucket on the left. I wonder what they are for? Seed containers maybe? Chalk to get a grip on things? Maybe even small 'smoke pumps' to calm down wasps in the trees of an Orchard maybe?
Also curious about that hand holding the pole between the 'Woman and the chap to her left. Is that 'her ' hand or his?
I wonder if I can find a painting of a 18th or 19th century orchard with farmers....
