AWJ props différentiation project

[alextheyellowthing]

Same as the RTD and Moffat era's Edward Thomas tardie, it's now time for the Arwel Wyn Jones tardie.
Little summary. So far, as i know, there are 3 main props, H, I and J, and, i think, 1fiber glass prop that as at least been used for promotion and as been molded on the I prop.
