I don't want to be a Pessimist but apart from Mainframes I've never come across a 'B'. I wonder if it's a Special or it was modified by a Third Party. There were Third Party Plugins for Tektronix 'scopes and also 'Normal' ones that were Modified for special uses.
There are a couple of Plugins for the 564 which look perfectly ordinary but are designated 'Engine Diagnostics' if I remember rightly. I failed to buy one recently
