Looking for a tube or transition...

Hey gang,

One of my rockets - an MRC Concept II Flare Patriot - lawn darted, destroying the nose and crumpling the upper third of the body tube. It's a favorite, as it has the interchangable engine mounts, and I would really like to repair this bird. However, the darn body tube is "non-standard" with a 1.75" OD. I've looked everywhere and cannot find such a tube.

So can someone

a) direct me to a place where I may find a 1.75" tube, and after that, a suitable nose cone?

or

b) suggest a means of obtaining a transition from the 1.75" tube to a standard type, like the BT-60?

or

c) give me a lead as to where I can buy a MRC Concept II Flare Patriot kit?

Thanks mucho!

You could also get a custom nose cone and transition from them, or buy them from Sandman who frequenlty posts to this forum.
