Dear Jim, from your previous thread i give account that the one fresh approach is the Ned Kelly saga. May i suggest that his gang shielding apparatuses have by no means any linkage to the implement under discussion; not in form, nor in resistence, neither in means. We can't establish the minimum comparison bewteen a 1/4" thick (tempered) plough comonents and a thin bent sheet of soft iron, circa four times thinner.
I would end by saying that, while Ned's and his pack adventure has proven pathetic, Panoleon's item still has an unproven explanation

.
Yours humbly
