Interesting to note that on two of the Weavers mine and the back damaged one. The bats appear on the right whereas most T4’s the bats appear on the left. I have identified 5 T4’s where the bats are on the right the bulk of the rest are all on the left.
The 5 with bats on the right are Spencer, Weaver (2), Moskiman, Shehan (1).
Doubt it’s of any major significance but thought it was neat.
Cheers,
John
