Found by Geoff Hancock in the Glasgow area. Note the reversed ‘N’ and ‘S’. There are many references to Port Dundas on my website – click me – but this product is most likely to be manufactured by Port-Dundas Fire Brick & Clay Co., firebrick, &c, makers, 44 Bishop street, Port Dundas, Glasgow. or Port-Dundas Pottery…
(Note – SBH – Please read this in conjunction with the Port Dundas Fire Brick Works as they appear to have been situated very close and indeed they may actually be the same site with Malcolm Paterson operating it prior to Murray’s and Co – for clarification if possible!).

Below – 1830 – East Cowcaddens Quarry. (Note – this map does not show the brickworks but it does refer to East Cowcaddens where they may have been situated. However, the advert dated 26/04/1822 above may infer that the fire brick works marked on this map may be those that were known as East Cowcaddens. ‘Canmore’ has these works detailed as the Port Dundas Fire Brick Works but they may have been one of the same but in slightly different timescales).
