Actualy I did ask if he had offered it to Devizes museum and he said he never thought of it but said museums had bought things from him in the past.
This episode reminds me of the photographer Dennis Grant King that worked with Keiller at Avebury.
His collection went to car boot sales in Devizes and we were able to recover some of it but the house clearance people said they threw out bin bags of paperwork as they didn't think they could sell it.
They did offer the NT a collection of finds that King had but the NT were not interested so they sold it privately.
