Looking at the 'Armies in Plastic' Rangers I was wondering what conversion potential there was - I'm not a huge Rogers' Rangers fan and that's part of the fun of 1/32s - the conversion potential. So this unit - in their brown coats - might be an interesting alternative.
Historical information on the regiment is at this blog where there are some Front Rank 28mms painted and here where an even more detailed history is to be found.

As far as I know Gage's were recruited from locals and the brown was very much a Yankee colour.
