I believe CSM had these made, or they were made, by another firm in Italy. I found someone who mentioned purchasing a set from them, sent an email and Lou responded that they had one set left.

The barrels are new 26", ICxM, 3" chamber in the white with ejectors. The barrels are set up for the later 21's I beleive as my earlier 21's forearm does not fit on the hanger in its current configuration. Needs some metal removed for the mine to fit. Also needs a small amount of metal removed on the lug to fit my older gun.

It might have been a great deal or I could have bought something I can't use on my 21's. Not sure at this point. As I said, I bought them to add a second set to my duck gun. I want to keep my 30" barrels in standard configuration but also I like to shoot the gun (alot) so I thought about trying to go this route to add another set of barrels without dropping a pile of cash on the project.
