So I ordered Trouble Coming on 7inch and it’s exactly the same design as the two in your picture, except orange. Link below shows the album artwork, but the artwork on Amazon is wrong, the right 7” arrives.
Definitely not sold out, I’ve just bought:
Royal Blood (Amazon Originals) [VINYL] https://www.amazon.co.uk/dp/B096TJMZ1L/ref=cm_sw_r_cp_api_glt_fabc_HRMZGRN4797VBFD15QBM
Don’t let the greyed out “pre-order” button put you off. Hit it and you go to your basket.
I've been thinking about that myself, I'm thinking about getting some router attachments for a dremmel, and then using a routing template for a real clean route! Here's a link to one that should work for a humbucker: https://www.amazon.com/StewMac-Pickup-Routing-Template-Humbucker/dp/B077K4XLNH/ref=sr_1_7?dchild=1&keywords=mini+humbucker+body+route+template&qid=1604498441&s=musical-instruments&sr=1-7
