Getting references after a company closes - 9 months and counting

My manager was laid off too and I am unsure who to use as a reference. I do not usually post, so bear with me. A colleague offered to vouch for me. How do you ask politely?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

I kept a note of my results so my references could be specific. They appreciated it.
