Wanted AMW 75/1700 Motor

[John Kemker]

Looking for all the parts. Willing to buy just casing/just nozzle/etc. Casing most important.

 

[jsdemar]

Need it to be the original certified case? Or is this is for research loads?

Doesn't Kenny at Performance Hobbies have a case?

Does not need to be the "original certified case." Needs to be functionally equivalent.

If you can't find one, I'll make you one. I have the AMW 75/1700 hardware set, probably 18 years old and well used. I can make sure it matches.

I have a bunch of 54mm Kosdon casings from Frank's estate sale.
What is the length of the casing you are wanting?
