Hi cga. Yeah, there are quite a few of us. It is very good to know. Now if only designers would take a good listen, huh? Thanks for asking about the coat. I'm not sure what the answer is to your question about whether or not the hood is detachable. I think it should. Whether it does or not, I can't be sure. I found these photos on the web quite some time ago and don't know if there is information about this one out there.
Personally, I have 5 vintage hooded coats. Three of them are too small now, but my daughter should be fitting into them soon. I found them all at thrift stores around St. Louis. I hope this answers your question, and thanks again. Wonderful to meet you.
