Kestrel and Northolt

Two boats at the gathering at Shackerstone last month were Kestrel and Northolt.

Kestrel appears to have been built for Fellows, Morton and Clayton in 1928 (but, according to the A.M.Models website it was cut into two boats in 1959, the stern remaining as Kestrel).

According to the same website Northolt was built in 1942 for FMC, then being acquired by the Samuel Barlow Coal Carrying Company. The website also says, "Renamed Sunny Valley for the film 'Painted Boats' and has remained so ever since". So how is it that it now appears as Northolt?
