The finish appears correct. Pontiac used a flatter/Duller Zinc Dichromate finish.
The triangular dimples look like the smoother original kind I mentioned earlier. The O in Moraine is the correct split look BUT looks like someone tinkered with the Delco Moraine stamp to make look it more defined.

I'll focus on the E in morainE as it's easily the most suspect. It's a little off axis from the rest of the word. It's sharp and clear and looks thinner than the R in MoRaine. Originally it would have all been struck with the same force and pressure as the rest of the word and the N is a weak hit right next to the hard defined E. A single letter would not have been hit harder like that originally. At the factory sometimes the stamp wobbled left, right, up or down as it struck that is why you see things like your M barely showing but the O and R are more distinct. The letters should show a consistant level of force or trailing force left, right ,up, down applied across all your letters. Your's don't. The L and C may also have been "clarified" by someone too but I would say it's an original booster that someone down the line tweaked.
