This is its slightly dusty replacement. A bit bigger than the dead one and in need of new cables and housing but it’ll do for now. Rides nicely on the 406/47 tyres.
While seemingly the same, that frame may be slightly different. I think I see a thickness-doubler weld gusset on the bottom of the main tube on the forward side of the hinge. That doesn't help your failure mode, but I think is an indicator of later, post-recall frames. The aft weld geometry may be unchanged but improved in quality, I don't know. Will be good to know where each frame sits in the recall chronology.
The hinge is pivot is also changed, if you compare the two.
If not already in the old bike, hopefully the new bike has stronger weld filler material and the whole frame post-weld heat-treated to bring back up to T-6 temper strength, if it's 6061-T6 and not 7005, the latter of which was designed specificially for bikes to not require heat treat after welding.
At least now you have disc brakes.
