The 1198 was supposed to have a brighter screen than the 1197....I have not actually heard any personal accounts to attest to this...

I wear a darker colored shirt so that my shirt's reflection in my 1197 screen does not affect my viewing.....

I would think that the same raptorcap that fits the 1197 would also fit the 1198...I do not think the bezel and casing was changed...
