These spare parts are for all recent model Bestest vertical style indicators ending in -3. We do not have parts for the older models ending in -1 or -2. Tesatast vertical indicators use the same parts with the exception of the dial.
Repairs: Special tools are required for certain steps in the repair process. If you'd rather have us take a look at your indicators please see page 30.
Parts for the vertical indicator are also used for the horizontal models. We show only the exceptions on this page. Other parts can be ordered from the breakdown on page 74.
