With regards to depot standardisation I would go with the following.
5304 to 5309 remain at Deptford for the 9
5324/25 - Spares at Washington for the 4/5 & 50
5326 to 5336 - Branded at Washington for the 5 & 50
5337/38 - Spares at Washington for the 4/5 & 50
As a result of the above 5243 to 5247 and 5255 to 5260 would transfer to Deptford for the 35 with the remaining being spares.
