A Question for Labour Weekend

As it looks like Labour weekend will be washout for sport flying, how about dredging your memory banks for some info on this interesting machine:

Recently Ivan Krippner posted a video of old home movies fearturing sport flying in the Waikato.  Early on in the video is this amazing looking aeroplane taxying with verve at Krippner's strip at Ngahinapouri.  From what I know it is a replica of a 1912 Curtiss Flyer powered by a Honda engine with a huge Ducati carburettor bolted on top to provide plenty of fuel.  And the date I have is 1975!

The top photo is a screenshot and here is another smaller photo of it.

I think it may have been built by these two fine 1970s specimens.  I think they were motorcycle racers from Cambridge and may have worked at Waikato University?  From what I understand they had no plans and drew it out on the workshop floor with chalk (shades of the Jodel D9).  Can anyone identify the two guys?

I also understand that it spent many weekends taxying and doing hops down the strip at Krippner's strip before attempting a flight.  They obviously got into the air but I understand a lack of fuel issue resulted in a landing in trees alongside the strip with not much damage (shades of Richard Pearse).

And later it was craned down.  Of course it was never registered and I think the then Civil Aviation Division of the the Ministry of Transport told our intrepid would be flyers to desist (shades of Geoff Williams).

Later it went to MOTAT where it was known as the MOTAT Biplane:

Here it is on display at a motor racing meeting at Pukekohe in the mid 1990s.  Thanks for the photo Peter.

So here is your Labour Weekend challenge - what can you tell us about this pretty amazing aircraft?  Who built it?  Who were the builders?  (They could well still be around).  Where is the aircraft now?  And are there any other photos of it out there?
