Wow! SRD is completely out of Aust razors... Call and see if they may have one not listed on the site and/or when will they receive a shipment. If you this is holding up your first SR shave, don't wait! Get one!! Dovo/Aust/Vintage/Gold Dollar. Just get a properly honed one to start to build your skills. You can ALWAYS get another and another and.....

https://www.griffithshavinggoods.com/ also has some nice options, new and restored. I have heard good things but never purchased/used a razor from them.

Enjoy!
