Hi David
Sorry, I missed your post. Thanks for that; those are some very nice photos. Very clear.
Hi Colin
I note in that eBay sale for the "DS" plates from NB that the prefix "I" is retained. Lends a bit of credence that the earlier "I" prefix was used in govm't service in NB perhaps?
That video is pretty cool. Something for every MLU-er there! Not only the Bobcat, the plates at 5:27 & 5:40 , but also those interesting fuel bladders at 7:00, the Mk1 Stalwart (24EK70) at 7:24 and the fine RCD shleppin' 20 pdr sabot at 10:51.
regards
Darrell
