Cheers, Tyrone. I lost the rest of the video from the main camera, hence the funny angle for nearly all of the video but hopefully the content is still useful to some.
You were right first time. the mystery items are the racks for the rubber (On road) track pads which the official U.S. army manual for the sherman advised you to fit as soon as you reached the theatre of opperation😃
Thanks for the confirmation. It's sometimes surprising how tricky it is to find things out these days. We expect everything to be googlable but it seems that tank details weren't on the list.
Cheers but I find it easier to take them off and spray them for the base coat, then hand paint the black pads. I guess it depends on the type of tracks.
