Hi, just wondering if anyone can help me identify this alloy because I,ve put a couple of flatspots in it when I clipped a pothole with my tyre under-inflated

The tyre fitter had to put tigerseal round the edge of the rim to keep it inflated (which isn,t good.)
The marks on the back are
709
7jx17h2
01 02
99 00
MADE IN ITALY B.17g AAA
My reasoning is ,that if I know what they are I,ll be able to get another,as I do love these wheels.

Fellow members help would be much apprieciated
