Hi MrSaffron,
Thank you for your information regarding the location of the missing cabinets, I can't believe I've never noticed the cabinet on Grovesnor Road, Billingborough before, despite driving by it on numerous occasions.
I would have never found Cabinet 4 as I never go down Blasson Way so thank you for that one. I had been told that there is a cabinet (7) on the Highfields Country Retreat Leisure Park but I too cannot pinpoint it on Google, so I will have a ride out there at the weekend to see if I can find the exact location.
Yes, both Cabs 2 & 3 have had a twin cabinet installed next to them within the past two weeks. What did surprise me though is that Cabinet 2 has had a much smaller cab (single) installed next to it than the original (double cab) but cab 3 has had a big double cab installed, much bigger than the original one which appears to be a single cab.
Once again, thank you for your help
