Just sharing some radiator sizes.
For whomever it might benefit.




These are just readily available small ones.

Adding to the list is much appreciated

Could be similar to the Polo III one you have listed, but I chose this as it filled the nose nicely and had in/outlets on the left with no breather.

Core size or outside dimensions?

The sizes one can find are a bit all over the place.
So either will do.
