Prolly a "dum dum" NOOB question re: Model 66

[Temptd2]

I'm in the process of purchasing a Model 66-7 and want to buy some grips for it - so can anyone tell me if this is a round or square butt gun? It's the 4" barrel.

The seller is supposed to tell me when he replaces the grips that are on it now, but I see some on eBay I'd really like to not miss in the meanwhile!

THANKS!

It is a round butt
