GP Horncasts

I have a couple of horncasts for GP. One I know to be original Italian one I have doubts about. The latter one doesn't fit.
The original one has the correct part number (22050086) and some FP casting marks (P1477) in addition to the Innocenti logo at the top.
The other only has the logo, which looks less authentic and the same part number. This doesn't fit. I'd say the hole centres for the screws are about 3-4 mm closer together and if you put it back to back with the genuine one the top corners actually fit inside the original one and the same at the bottom.
I suspect it's Indian or remade.
Is the Indian one known to be narrower or differently shaped?
