I had one that featured the "Daniel Rebour" presoftening and was so stamped. I recall there was some debate as to whether these "swallow style" were '
real' Ideale models or something done aftermarket, since there doesn't seem to be any documentation such as mention in catalogs or an actual model number. But, mine like this had a stamp in the leather just above the cut, so it sure looked 'factory' to me. I sold it for a pretty penny on eBay, the winning bidder was a local (for his fixie,

).
