All things ballooning
Lindstrand Makes a 60,maybe a 56. Firefly makes a 56.Cameron makes a 60 i believe.
Hope this is something like what you wanted to know.
I have always been curious about the Stumpf replacements. They look really cool.
Also Ultra Magic makes a 56K
Look into National. I believe the owners name is Phil Gray. He can make a 65K I believe thats pretty close in design to the Aerostar Aurora. If you want a FAA certified balloon that is, but Casey is right also about Paul Stumpf, except those balloons are experimental if it matters to you.
National makes a 65k standard shape or a 60k racer. We are very affordably priced and several pilots who were flying Aerostar have switched to National once their envelopes are "retired".
I am a National dealer and would be happy to answer any questions you have about them
I just found on the website www.balloons4sale.eu , a new UltraMagic H-42 ( built in 1996 ) 0 hours flown, only 2 or 3 inflations. Possibility for attaching banners to envelope.
It's owner is Pieter Kooistra from Holland... here is the link to the site of the UltraMagic H-42:
