Various volunteer units were raised by "patriotically inclined" pro-Hanoverian nobility, gentry and clergy during the '45 and the Yorkshire Blues was one such unit. The money raised by the patriotic association in York, £31,420, funded four companies of infantry, each of 70 men plus sergeants, corporals and drummers. The unit lasted about four months. The name described their uniform, which was blue faced with red and of fairly simple cut and design without lapels.
This blog post: https://defendingthelegacy.blogspot.com/2017/01/flag-of-yorkshire-blues-regiment-in-1745.html put me onto a contemporary print, which unusually details the design of the regiment's flags, although it does not give the colours used. The coat of arms of York in the centre is known but the field of the flags is not. That blog post suggests blue, which is as good a colour as any and probably more likely than most, and I have followed that in my reconstructions of the flags. I have also produced an entirely speculative union flag design; it is quite likely that no such flag was carried but I like to be thorough in these matters! I have also shown the design with the inscription plus one without; the contemporary print shows both and it is not clear if both were used or the design with the inscription is entirely the fantasy of the print maker. One can never be sure in these matters!
The unit saw little action, mostly being used for garrison or escort work, as far as I can tell, but I would be keen to hear more if anyone does have more information.
