I checked with the source and he said it would be ok to post his email address here.
His name is Harvey. The part number is # 60478. This fits the Autographic 3A, model C. Probably fits other models as well but I don't know for sure. He has other old bellows for sale too. You'd need to send the measurements.
Thanks, Kevin, I just e-mailed him. I don't hold much hope he'll have something to fit my 1926 (or older) Ica 225 Ideal plate camera, but one never knows...
I wanted to thank you as well. Harvey replied to my inquiry, and I have sent off for my new bellows.
I really appreciate your sharing this information with us.
