For starters.

Hi. I see you have copied my photo from Old Pictures of Chesterfield FB group, the one showing the Sherwood Foresters party. I would like to ask why you think this picture was taken in Ashgate Drill Hall? My reason for posting on FB was to try to find out where it was taken as I have old family members in the photo. We had previously discounted Ashgate Drill Hall as looking at the windows and roof line and the size of the hall it did not seem to fit. However, if you have knowledge or anyone has other photos from a similar period that can prove or disprove, or have knowledge as to where else this photo could have been taken I would appreciate it. I am typing on behalf of my 86 year old father who has been trying to answer this question now for a few, years. Any knowledge would be great.
