Army Universe New Olive Drab Alice Pack Frame with OD Straps

Is this made by Rothco? or some other company?

Is this made in the USA, or a foreign knock-off?

Will this frame fit the medium alice rucksack? i tried putting my med. ruck on my large frame and it was a no-go so i'm looking for a med. frame.

Can this be used w a mollee assualt Pack
