Anyone know this artist?

Quite some time ago, I purchased this small watercolour at a local auction; didn't pay very much. I tried to find information about the artist but was unsuccessful. I found another work by him on line that had sold in a UK gallery (signature matched) and contacted the gallery and they responded, but they knew nothing about the artist nor did the seller whom they had contacted for me.
I believe the artist to be British; possibly late 19th/early 20th century.
It is interesting that on the back of the painting it appears to have been sold to a W.J. Frazer in Newglasgow, Nova Scotia - appears as if it might have been sent to him with his address noted on the back. What all the other numbers & such are, I have no idea.
The painting, as noted on the back, is Grimspound, Dartmoor which is the remains of a Bronze or Iron age settlement in Dartmoor in Devon.
Altho a bit difficult to see, the signature on the Polperro & the Torquay paintings (found on line as well) also match the one on my painting.
I also saw somewhere that this artist might also have painted under the name William Greenwood? But I am not totally sure about that. (It was awhile ago so Greenwood might be a bad memory)
If anyone knows anything about W.G. Cole I would appreciate any information about him.
THANKS

 

Just a note - I find it interesting that in his signature, he sort of "outlines" the WG and then just prints the Cole. When sold to me at auction, they had not seen/deciphered the "outline" and sold the painting as by MR Cole (I think that's what they listed the signature as).

 

I didn't find a soul of the last one. Anyone can find soul of that painting?

 

There appear to be a number of his paintings floating about on the internet. And then there's this. Is this you?

The thread was posted on 2014..... now it's 2018.
However, they have the same last name....

 

I can. But I think that is the sold one, which he found a picture of online.
