There is no original model, both versions exist depending on the models and years of manufacture.Both models have exactly the same size, only the appearance changes.
I think the Philips finish is the best, the screw does not mark when tightening and there is less risk of snagging than with a slotted screw.
Stainless Steel.
Compatible with models Rollei 35 35S 35T 35SE 35TE.
The camera shown in the photo of the installation example is not a product.
