Meldrew Mine took 9 days from shipping to delivery. It was a long nine days though. :-)
Things to consider are how you are going to move the crate from wherever the delivery driver leaves it to where you plan to unpack it. It’s heavy and awkward - I had to heave mine up three flights of stairs so trust me on this! And make sure you unpack it close to where it is going to live - you probably don’t want to be carrying the unpacked machine from one room to another if you can avoid it. You’ll need a fair bit of space to unpack it comfortably.
Other things you might want to consider getting are Molykote grease, the steam and water joysticks on mine arrived ungreased and they were much happier after lubrication. You’ll need this later for greasing the cams after chemical cleaning. An adjustable wrench - preferably with soft jaws (or just stone any sharp edges and burrs and tape them). If you can find a smallish stubby one that still has decent jaw capacity, maybe 40mm. And I find a tamping stand handy.
