Coventry Trams

I don't think the above is a Coventry Tramway photograph! The uniforms are not the same as in this one taken in Priestley's Bridge depot of Clippies & office staff:

There seems to be an age difference as well, the ladies in your picture Manor House look a little older. The plot thickens ! The Coventry uniform is single breasted whereas the girls picture they are double. This is a picture of Roy's grandmother with a double breasted uniform, perhaps I should look at Midland Tram depots.

I suspect you might be right 20A-Manor House, but I also think that the uniform varied year by year. There seems to have been a summer and winter uniform. The drivers and conductors may have had different uniforms. I can't find a perfect match between many photographs of Coventry Tram staff. Male or female. link to Coventry Tram site
