Sorry mate Im not sure as this info is straight from SB Manuals And sales sheets. My LV30 on the 62 Turner is Australian Marked but it doesnt say made in Aus and it is titled Lauson only. When I find the plate ill post an image. I have seen later Nos Engines that are marked US but cant remember the city of manufacture though. Not my forte kirby or lauson, Only some of the mowers they were used on and the info gained on rebuilding my Turner/ Lauson LV 30. Sorry there really isnt a lot of Factual info on them grumpy:)
