Just my gut reaction on seeing the images ....
It's a carving of a barque , perhaps one with a shallow-ish draft , having the curious feature of a sub-gunnel fender (or 'bumper' , if you will) at it's bow , perhaps for navigating 'shrubbed/treed' areas of inland &/or tidal waters .
The calligraphy used by the engraver of the metal tag seems to be in keeping with 'it' (meaning the calligraphy) being within the timeframe engraved upon it .
In my opinion , this piece will be a hard sell as authentic + a high price (without it's provenance) online or otherwise , if represented as an 'official' model from the company mentioned .... this is not to say that it does not have high appeal with the nautical folk-art nitche .
Since the carving skill exhibited by the carver of this item is not too great , I'd consider that it may have been made by a sailor , for reasons unknown , and later tagged with the brass that's on it today .... carving was a most common trait/hobby for many shipboard folks , during the sail era .... often times for trading/selling at ports where they'd lay up at .
I can't really tell from the images , but I'm curious to know if there were some other metal pieces/elements (on the sides of the ship) that are missing now ?
As far as dating it , well , I guess that one could use a bit of science to discover the type/age of the glue that appears to be still holding the pieces together ...
Cool item , regardless of what it turns out to be , kjtorris .
