Bob here is my old Swarovski non phase-coated 7x30 SLC

Quite a bit different from the picture AG shows. SONA said they could not up grade mine to phase-coated and if I remember right they said if it had been the 8x30 SLC they could.
...
In their early years neither the 7x30 SLC nor the 8x30 SLC had phase coated prisms. After the 7x30 was discontinued a new version of the 8x30 was brought out with phase coated prisms.

My understanding is that they were upgraded with swarobright prisms and coating current to 2013, which is why the new SN. I will reach out to SONA to find out more details.
Right, see post #7. The owner paid $500 to have the non-waterproof Mk 1 upgraded to a Mk IV waterproof model. By contrast, my original Mk 2 (waterproof) binocular purchased in 1993 was upgraded to a Mk IV in 2011 for free.
The only reservations I have about the 7x30 SLC are it's relatively narrow FOV (378') and short eye relief (14.5mm). Other than that, it's a nice piece of equipment.
