70 series Gold Cup main spring housing type?

[218bee]

Specifically, which type of Mainspring housing came on a Factory-original 70-series Gold Cup NM 45 pistol?

Have one that's all original except MSH and want to get the right one to correct it.

Thanks

Flat, with lengthwise striations. I probably have one or two if you need one.
