There are several descriptions, prints etc for the uniforms worn by Beon and Damas chasseurs, slight changes may have occurred when the British Army took charge. I have chosen to keep the orange facings for Beon, and orange sword knots for both units to confirm their earlier service.
I think these Hinchliffe Austrian Jaeger castings have painted up quite nicely as émigré chasseurs. And no army can move without a vanguard, and suitable troops for outpost duties. MGB
