The Winter bank indicator is a simple instrument that works purely as a bank ball similar to your spirit level. However the excellent craftsmanship turns this instrument into another Winter masterpiece. Maybe you have a panel space to fill or you are looking for an additional reference point for flying.
This Winter bank indicator has been designed to fit on top of a standard 57mm instrument hole mounted from the front of the panel.
Its recommended for when there is not much space behind the panel and although it does stick through a 57mm hole it actually only needs a 33.5MM hole that is 13mm deep.
