L-29 Historical question

It sounds to me you are asking a question about the Stutz, not the L-29. Thus no answer on this forum. Maybe you should clarify your question if it is about the L-29.

It has been 5 years since this post and surprised that no one has yet attempted to take a stab at the question? I am still in need of an answer "official" owners and historians. Thanks!

Bringing this back to the top in hopes someone with historical background can help answer my question? Thanks.

This is a "which came first" type of question.

I am trying to establish just which auto came out first with the X braced frame.

As for the first "introcuced for sale" car goes, that would be the 1929 Stutz Blackhawk which was launched in January 1929 as opposed to the Cord L-29 that launched in August that year.

But, what I am seeking is which was first with their prototype? I am assuming that the Cord was in the 1927 prototype (and assuming Snow - Van Ranst had the X in place then) but does anyone knows about the Blackhawk... if it would also come out that year or prior or later? For some this would make a determination as to which car was first with the X chassis since prototypes are being considered in my research.

I am curious because books have often stated the Cord was first with the X frame in America (in Europe it came a lot earlier from France).

Any help greatly appreciated!

Many Thanks...

Eric
