This is such a good reminder of just how hot parts of a rocket stove can get and how important it is to inspect things carefully, and design things so they *can* be inspected carefully, particularly when you're experimenting! I've been gradually collecting the things I'll need to do an outdoor one for learning on, but I'm totally cool with learning from other's mistakes! Thanks for the great pictures, Gerry.
Long story short, I don't think this is ceramic fiber blanket, superwool or whatever else you would like to call it. It may be a high heat insulation suitable for oven temperatures but certainly not what will work for the extreme temperatures of a heat riser. Sigh!
It looks like your stove manufacturer used a lower grade insulation. I'm not surprised that there are variations on the construction across different models, but it's the first I've heard of it.
You can find superwool online at Amazon for reasonable pricing. If you are unsure or not willing to experiment then that's likely a better source for you.
Sure, you are welcome to share my thoughts, thank you for asking. Thanks for your continued support as well, I greatly appreciate you and the gang over there and all the support over the years. Let me know if there's more I can do to help.

I have had one for a few months but not actually fitted it yet......
