I suspect it is a top or side gating, as I see some grinding marks on the edge of one of the handle areas in a pic above....
The Raised Number (size ) is interesting also...
There were just sooo many different foundries around, it is many time difficult to identify 'who done it'....
With a wide range of 'casting' quality, weight etc.
Other than the ragged holes, the rest of the casting of the piece looks to be fairly nice.
Maybe someone else will stop by and give a shout if they recognize the design.. :) I can't quite make out the Number on the Handle... :)
