Brass rivets Atwater model 20

[HiFiCanada]

Anyone know of a good place to buy brass rivets and screws for antigue radios. The rivets on the tube sockets on my Atwater-Kent model 20 are letting go, and I would like to have as an original look as close as possible. Any advise on the brass rivets and the riveting tool would be great.
At first I was thinking of using a pop rivet tool, but that would break socket as it pulls through the pin.
