I don't believe so, as the model 1899 designation was changed to model 99 in 1920,
At the same time as the 300 Savage was introduced.
I suppose it is possible that's some leftover 1899 parts may have been used to assemble a 300 Savage takedown model 1899.
I have not seen any others than the one on gunbroker, so I would tend to think that they would be somewhat rare.
Frankly the one on GunBroker is a poor specimen to my way of thinking. Used and abused, and Bubba'd screws to boot.
I would pass on it. There are still nice ones to be had out there.
