Do you really consider this FF Concept, or is it only a 2d choice, for you?
It seems that you were first attracted by the 45 mm FF, and that Vintage FFs are more in your " 1st choice " category.
If the FF Concept is only a 2d choice, let it pass, my friend.
2d choices are often the worst, and an eternal source of frustration.
I can't answer to your questions about the FF Concept rubber parts, but if I remember well, our firend Oliver owns one, and he may answer to all your questions.
As for Vintage FFs, where are you located?
I may, maybe, be able to help you.
Best,
Nicolas
