Stallion, dear chap, that is my point - I WOULD NOT EVER pronounce "our house" as "ower owse", it would be "are ouse" ( "ou" pronounced as in "out" ) - if anything.
If I saw "ower" written ad dialect I would read it as OVER not OUR and pronounce it with a long "O" sound at the start. If I used the spelling in Bradford's dialect it would be in a sentence such as " Ey up, are kid! Cum ower ere", but in real life I would write it (H)ey up, our kid! Come over here.
Quack!
