Small Cast Iron Kettle Marked

I am unfamiliar with the markings on this kettle. It stands 3 3/4" tall and measures 6 1/2" across the top. Pretty heavy. Bottom has 1501 1 and other marks...Any help?

 

Grainger & Worrall? Pure guess.

 

The logo in relief looks, at a quick glance, like a long-eared dog sitting upright in an iron pot while wearing a bow-tie. That would be fairly unique! Turning image 90 deg. CW same iron globs look more like "6 IN"

 

Thanks...I will have to look at it in the light more tomorrow

 

It does say 6 IN. Looks like there is a mark under that. Can't really tell what it is...a persons head with a crown? Hard to say.

 

No it is a winged piglet climbing the stairway to Heaven. Or more likely is just a sprue or riser location from the casting process.

 

I'm seeing either "SIX" or "6 IN"

 

Someone on a cast iron group said this was most likely a modern import
