#3567 is a stunner and have not seen it before as busy as that. A wonderful photo at maybe close to the end of the horse era. The trucks look shiny and new. Gosh, how much busier could it possibly be. # 3568 is an old favourite showing the old poplars (I think) around the moat. The view direction is the same as the photo I believe but I suspect from a little further south and standing in an early Bradford Street. Come to think of it, the sidewalk corner at the bottom of the picture might be the corner of what would become Sherlock St. If this is correct, then we would be looking up to the corner of Moat Lane and Moat Row and that would be the Manor forecourt; outside of the moat. Upper Mill Lane would be up there and perhaps the buildings ahead on the right might have been Manor Mill related. Maybe unused by then. The two images are very complimentary. You can see the old wooden fence around the outside of the moat and the Poplars would be on the inside of the water.
In picture #3568 there should be a leat from Highgate dam, somewhere in the foreground (maybe below street level at that time, or maybe dis-used) that lead to Lloyds/Astericks mill pool and the top of the pool may be behind the wall on the right, if it was still there. This pool fed the watermill on Lower Mill lane. The lane is still there.
