Who can remember this?

The following photo of the gates on the Eastern side of Prospect Oval was taken in 1923, just one year after North Adelaide adopted Prospect Oval as its home: 

The current gates on that side of the ground were installed in 1980 and were named the Ken Farmer gates in honour of our legendary goalkicking genius and master coach. This picture was taken at the opening of the new gates and includes North Adelaide legends Harold Hawke, Ken Farmer and Ron Phillips: 

Did the original gates survive until 1980, or were there other variations in between?
