Welcome from Central Mississippi. Your quilting frame is beautiful as is the shot of ya'll quilting with it. If it was made by a corporation,I suspect it would be tagged in some way. I like the Amish maker identification offered by IceBlossom. Do you know if it was bought in Atlanta? Perhaps a call to older local quilt shops asking about quilting frames would get you a good response regarding your beautiful frame.
Is there something about the quilting frame process that you need to know about? We might be able to help with that.
