I would bet that the set was altered at Steve Maxwells place. If not some other drum shop did it because Ludwig has no custom shop. The rail is the new Maxwell version and as Bermuda said the brackets for the bass drum legs are just regular tom mounts.
Ludwig puts the badge at the back of the bass drum(close to the player) and has done it this way since they introduced the modular hardware around 1984. The big modular mount had to be mounted towards the front of the bass drum to be able to make the toms not come too far forward. Because of this Ludwig had to retool the machines to put the badges closer to the player. They just never switched back. It's the same for the toms too. The B/O badge that replaced the keystone badge in mid 1969 had to have the grommet drilled higher to accomidate the bigger badge. They never changed the drill posistion(and will not even on request) to make the smaller new keystone badge look centered. This is why that set has the badge up high.
Someone obviously had the bass drum ordered virgin and had someone else install the bass drum legs and the rail mount. Ludwig also will not center a bass drum cymbal arm so if you want it like the old ones you have to have someone do it or do it yourself if you are comfortable enough. I am not and when I ordered this brands new CM Champagne set, I ordered the cymbal mount seperate and had my store install it where I wanted it. That looks like a nice set with some bonus add ons. I'm not crazy about the look of a two bolt rail as classic Ludwigs always had a 4 bolt.
Here is my new set made to look like a modern version of a 1970 set. They are CM shells and I think it cme out pretty good. It sounds awesome and I gig it all the time now.
