Bickered,
I'm not aware of any plans, and I'd be very surprised to see Win. or Browning introduce another run of Creedmoors. But, as you likely know Win. is making limited runs of their "1885 Limited Series", which is essentially the same as the Browning Traditional Hunter rifles, which feature a high-wall action. These come in several calibers (.45-70, .38-55, .405W), including the 45-90. And the 45-90 has a 34" barrel like the Browning Creedmoor. Only the barrel on the .45-90 version is made by Badger, which I confirmed with Ernie Stallman, owner of Badger.
The Win. 45-90 1885 Limited Series has the following features:
Finish: Blue
Receiver: Blue, Drilled & Tapped
Stock: Walnut, Satin, Checkered, Straight
Sights: Marbles Blade Front & Rear Tang Mounted Peep Sight
Barrel Length: 34 with Semi-Buckhorn Rear Sight
Overall Length: 50.5
Weight: 11lbs 13oz
Butt Plate Recoil Pad: Crescent Buttplate with Strap on Top
Additional Features: Octagonal Barrel
Suggested Retail Price: $1,585.94 (but you can find serveral on the Internet auction forums for around $1200 - $1300.
What I don't like about these is the sights are not intended for silhouette shooting. But one should be able to easily switch out the rear tang and front sights if the intended use is for silhouettes. Also that cresent buttplate is sure going to hurt when shooting it in a prone position.
