The majority of West Coast Okeh releases had matrix scratched in instead of being stamped. Remember Okeh had an LA office & studios where Williams, Watson, Richard, Triumphs etc recorded, most of their have scratched matrixes.
Yes there are 2 versions one plain white other with square on label. There my well be boots out there but generally it's a low cost record so maybe not.
Excuse me, this is a 1970s boot ?

Don't forget there will be lots of add-ons with air freight, you must always ask what they are, such as customs clearance, files costs, pick-up, delivery, consolidation costs, etc.
You should plan this as carefully as you can. For a couple of singles post is best, for anything from 20 to 100 someone like UPS (NOT USPS) try one of the parcel discount places like ParcelHero or Parcel2Go they'll give best rates. For larger amounts try an air freight forwarder like Ziegler I've shipped thousands of records with them.

If I were you I'd start weighing lots of singles so you can build up an idea of whom you would ship with so that when you've done your buying you can start the shipping process straight away. I have 35+ years experience of worldwide air & sea freight shipping. There are other things you can do to reduce costs. Good luck.
