Chateau bottling didn't take off until the first growths (with d'Yquem) led the way in 1924-5, and it took years before it became standard with lower classed growths.
Many years ago I bought a Ch Batailley (5th growth) bottled by Averys. They used their own standard printed label with 'Batailley' added with a rubber stamp. I can't find my old records but I think the vintage was '50s
I think The Wine Society only stopped on-site bottling in the 1960s
I broke my wine teeth on English bottled claret with designated château names, mainly from the 1952 and 1953 vintages, and many were very good indeed, especially from the latter vintage. I also seem to recall that most of the clarets which my father bought from the Wine Society up to the late 60s were their own bottlings, including my favourite Château Cantemerle.
Some Belgian wine merchants, especially Vandermeulen, were famous for their own bottlings of famous clarets and Burgundies up to about the same time; these are still sometimes found in auctions. I believe that Grafé-Lecocq of Namur still offers own bottlings. It was said that Vandermeulen had recipes for "improving" wine, such as a dollop of port here or a bit of cassis there. Of course no English wine merchant would have done such a thing.
