Marton Mills has the Buchanan Tartan in the Ancient version on their stock fabrics list.

The problem with trying to find a specific Tartan or variety of a Tartan is that there are very few weavers who offer Tartan in P/V.

We just had a discussion on this subject last week. The end result is that if you want high quality Poly/Viscous Fabric in Tartan suitable for kilts you have only Marton Mills. Other weavers do have P/V fabric but it is usually very light weight and suitable for ties, scarves etc. and not for kilts.

Please be aware that the web is full of ads that say they have heavy weight P/V. They also claim to have authorized Tartans. These claims are usually found to be less than reliable.

Anyone who claims to have P/V in weights higher than 12 oz are probably confused.
