[52Allard]

Great question Ol'Ron. Yes - all the production Allards that I'm aware of up to the K3 and I think the JR model had the split axel front suspension. I know that seems really weird but Sidney Allards roots went back to hill climbs and rough roads of England. If you wanted a lot of suspension travel and didn't have lots of dollars to spend, that's the way to accomplish the task. For a more modern equivalent to this style of suspension think Ford truck twin I beam suspension. Basically the same thing but a little better execution with the Ford.
My car does have arrester straps although they need to be replaced. Believe it or not, I do have the document where Sisler requests them from Allard in England - attached.
