OK anorak time, borrowed an original & boot......
1. The boots are see-through dark brown vinyl when held up to a bright light.
2. The originals have a conjoined "AS" in a perfect circle stamped in the run-out, on the boot it looks like a hand-drawn circle with a ‘zl’ and little ‘c’ in it.
3 The delta mark 68365 (68365-X) & T-101-A (T-101- on the originals are approx 4 - 5mm high, on the boot they are approx 2-3mm high.
4. Although almost the same shade of yellow, the original label is matt; the boot is glossy, particularly the few mm around the edge with the run out which is quite shiny.
5. Around the central hole the step down on the boot is almost continuous, whereas on the original is it for 2/3 then plateaux’s out for the last 1/3.
6. On ‘No time’ the run-out is approx 12mm on both copies. However on CGOTM, it’s about 9mm on the original & 12mm on the boot
