 It's my understanding that the numbers should be on the turrets, as indicated in the attached photo.  But we're talking British parts from the 1970s here, so quite possibly the person who made any particular item might have 'neglected' the numbering process for one reason or another.

Since it is rarely possible to order new distributor components for a JH, the only way to assess the utility of a potential replacement part is to compare its specs to the desired ones.  And while the shop manual lists the basic specs for the several distributors used, the way these specs are written does not entirely coincide with the descriptions that Lucas would have used.  And apparently no one ever bothered to provide sufficient information about the vacuum capsules.

Finding answers thus becomes a matter of asking owners for information, and hoping they'll respond.
