I separated each text using photoshop to make it dinstict characters to be able to use it in online font recognition software, but with no success.

Handel Gothic  Suggeriti da JoCatalparo 

When I saw this yesterday - all I could think of was Handel Gothic - because that is definitely a Handel Gothic "r". Is stryker a company - and would have had this as a logo made for them? I have a feeling this may not be a font, and if you want it you would have to recreate it.

Better match than Handel Gothic is Newtown, but still not exact thought someone might come up with original. Actually I have seen somewhere S like that which touched matching characters like t above too, but not being able to find now.
