[ANSTHRLD] Conflict Double Check, Please?

[Steven Hall]

Hello all, it's that Snorri guy.

I'm a little rusty on the Francois Method these days, so I'd like a
double-check on a blazon, please?

Per pale purpure and argent, three turtles counterchanged.

IIRC, default on turtles is tergiant, so that's unneeded in the blazon.
Best Gróa and I can figure, it's clear, but I wanted to be sure.

As aforementioned,
That Snorri Guy
