BudsGunShop.com - where can I find one?

Several available here

At this time Marlin is not producing any firearms they were purchased by Ruger "Ruger plans to have new centerfire Marlin lever-actions on dealer’s shelves before the end of the 2021. Initial plans include building Marlin 1984, 1985 and 336 models, with the Model 50 .22 semi-auto coming later, presumably in 2022.
Caliber-wise, the good news is that Ruger is sure to carry on .30-30 and .45-70 in their new levers"

Your best bet would be to either click on notify me when available and Bud's will email you when they receive a shipment of these in. Or if you don't want to wait I'd check GunBr0ker, they're a site that allows private owners and small shops to sell their products so they usually have rare and hard to find firearms and accessories. You might get lucky on there. Hope this helps.
