Hard to get an exact date or serial number range when it might have happened. In his book on 22-23rd series, Robert Neal says best guess for the change over to R11 production to start was in December 48 and done in increments as B-W was able to deliver units.

To further confuse, if owner wanted to buy it there was a kit made available to dealers so they could make the change to earlier cars or earlier years if the R9 had exhibited the lockup issue.
