Unusual looking HMV 102 ? Maybe India Teak HMV 102 ????

I think the same. The 102 tinplate horns are pretty stiff by themselves, and the only thing they need is the angled lid to 'complete' the sound system, so the motorboard and the angled lid form the final expanding flare at the end of the horn. The base case doesn't add anything to the sound.
