Every lot was sold in an auction that saw more than 1000 people walk through the Museum.

Cowra War Museum, Trevor Davidson, said the weekend was organised chaos.

"It was a very successful weekend, we're very glad the rain held off."

"We sold everything we had up for auction, our Model T postal van sold for $21,000, the red and black Model T sold for $22,000, our 1974 Dennis fire truck used in the Darwin Bombings sold for $25,000 and one of the steam engines sold for $40,000."

"It's amazing to see how much people were willing to pay for items, some of the signage was selling for $800 to $900," he said.

Mr Davidson thanked those who made the day a successful as it was.

"Rotary did an excellent job catering the auction, I think by the end of the weekend they didn't have anything left. The police did an excellent job directing traffic and getting people in and out or past the museum if they needed," he said.

Rotary Club Director Larry Walsh agreed the day was a success.

"It was a very successful three days, we're very pleased with the results."

"We sold just about everything, the profits made will go back into the community through various groups and donations," he said.

Mr Davidson said the War Museum would remain closed while the site is cleaned and rearranged.

"We'll be cleaning up and rearranging and repositioning the pieces before we re-open."

"We'll also be looking at expanding the war and rail pieces, getting more artillery and military vehicle pieces," he said.

The Museum is set to re-open June 1.
