alexander_busek (me): Is this [i.e.: "jerry-rigged"] a now-acceptable variant of jerry-rigged - itself a WWII variant of the centuries-old jury-rigged?

Pelham (you): "The phrase "jury rigged" has been in use since at least 1788. The adjectival use of "jury", in the sense of makeshift or temporary, has been said to date from at least 1616 when it appeared in Capt John Smith's The General History of Virginia, New-England, and the Summer Isles published in 1624. [...]"

I had thought that my question - concerning "jimmy-rigged" - made clear that I already had an understanding of the lexicology of "jury-rigged" and "jerry-rigged."
