If you look at Kate's map in post 30 there is a long narrow building on the lh bottom corner of Back Henry Street. This has a back extension on the left and probably a yard on the right. Going up the back street there is then a building on the left after the yard of the building on the corner. This ties in with the drawing of the back street which shows probably a yard wall then a small building, on the bottom left of the picture.

This suggests that the tripe shop was on the bottom lh corner of the back street.
