Figuring out a mismatched Oyster Precision

So, here we go. I picked up this little (30mm) Oyster Precision the other day. The case is older than the dial, mid 40s ref 4270, with a 60's ish T-Swiss-T dial. Judging by the overall state of the watch it has been this way for a long while. I am assuming swapped out in period. However, I cannot for the life of me find the actual 60's reference it would have come from.

It is basically a Speedking dial, but with not marked as such. I can find similar with date, and similar as perpetuals, the same but larger (32mm) but none in 30mm. However, there is one almost identical combo, mid-40s case with the same dial and hands on Ch24 https://www.chrono24.co.uk/rolex/oyster-precision-shock-resisting--id21567067.htm, which leads me to think maybe this was supplied by Rolex as an in-period replacment dial. Thoughts?

Cheers Canuck. Yup, its a cal.710 which evolved from the Aegler 700 (sub second version) and was used for years. (I'm currently on the hunt for a pallet for a 10 1/2 hunter centre second movement in another Dennison cased Precision I have).

The case serial definitely places the case c.1944-45, but the T-Swiss-T dial is defo early 60s onwards.

The confusing thing is I cannot find a matching reference for the dial anywhere. The original dial would have been branded Oyster Elegante. Its been replaced, but the fact I cannot find a single matching ref using this dial on a later Rolex makes me thing it may be some sort of service dial. It's defo a genuine dial and unmessed with, just not the one that originally came on the watch.

This is the dial it would have had from the factor, or similar at least.

That second one is awesome!
