What happened to model of record-breaking Peugeot?

It has been brought to my attention that the model of Malcolm Campbell’s Peugeot Grand Prix Type L76 that was on display in the National Motor Museum is no longer visible. I wonder where it is?

This model was made by the Roger brothers of Slough in the 1920s for Campbell. It was an accurate large-scale copy of the Peugeot driven in the 1912 French Grand Prix by Jules Goux and afterwards raced by Campbell at Brooklands. Its streamlined tail is said to have been added “for record-breaking” but it did not have the distinctive radiator cowl.

Campbell took the 40hp and Class G records at the Track in October 1920 and won the Summer 100mph Short Handicap at 89.5mph, an Essex Lightning Long Handicap at 95mph and finished third in the August 100mph Long Handicap. Then in 1922 it gained a second place lapping at 103.11mph, and in 1923 won the Easter 100mph Short Handicap at 92.2mph lapping at 101.43mph. The car was then offered for sale at £500.

It passed into the hands of Mrs Oliver Stuart-Menzies and she used it at Brooklands in 1923-24 but had no wins. She also drove it up Shelsley Walsh in 1924 in 66sec, although she found the old car heavy to steer.
