I just came across this very interesting symbol while I was reading Kushan History and thought like sharing.
It is a Quadent (fork with 4 teeths) and a horse shoe.
The symbol is still very popular among the Gujjar Community of Today. If you search ‘Gurjar Symbol’ online you can find pictures of this being used by them. They use it extensively as a sticker on their vehicle windows and various other places.
The symbol seems to trace its history from Kushan Era coins -
Kushan Empire ruled a large territory covering Central India, Bengal Region, Baluchistan Region, Central Asia, Western China etc. from 3 capitals - Kapisha (Kabul), Pushkalavati (Peshawar) and Mathura.
I feel this symbol will be a better representation for the Gurjaras instead of the generic mandala design that is currently being used.
