Very Early Fire Alarm Coded Pull Station

I was browsing eBay and came across what appears to be a very early coded pull station:

Unfortunately, the interior workings have been removed. I’m thinking this could be an early Edwards design, since it almost looks like this design could have influenced the later 1251 series coded pulls. Does anyone know for sure who manufactured this station?
