The mail catching apparatus at Blisworth, scaled from a section of linen backed map in my possession is:
Measured to the North from the centre of the A43 bridge. Down line 324 yds. Up line 330 yds. The postmens huts are shown preceding the apparatus by approx 6 yds in each direction. Should you wish to view the drawing/map and scale it yourself, you may.
Thank you David - I would like a photo of the track, map markings and huts area. Quite happy to journey to you to do this given you are not to far from Blisworth where I live. I have a weather-permitting break starting Thursday so either could do this very soon or early in new year - what do you think? My phone is 01604 879199. Regards Tony
