Perfect timing for this topic, as we just picked up the remnants of our seats & cushions from the upholstery shop, where the seats have been rebuilt with new leather and modern foam padding. We noticed the paper labels on the underside, as shown in your photo #5560. I will grab some photos of ours soon. The name on the seats surely must be their manufacturer. Do we know anything about the manufacturer? We have a date stamped on ours, too -- presumably the date the seat was manufactured, right?
