The most I can tell you about that particular chime is that it appears to be a very old & very rare Edwards one & that it could be a (possibly exclusively) Canadian-market device going by the older Edwards “E shield” logo on the bottom & the ULC sticker on the middle respectively.

I have one of these, not for sale currently. Mine does not have the canadian sticker.
These are definitely older - they use the early style square mounting backplate that some of the older generation bells and horns used.
