I have two Albions, one SLK High Head Dressage, and one K2 Jump that are 20 years old this year. The dressage I sold and then went and bought back, and the K2 Jump is identical to one I ordered in 2004 for the same horse the SLK was bought to fit.
I love them both and they fit me and seem to fit the horse (I am frustrated at the moment because my beloved saddle fitter seems to be ghosting me ) When these were new, I had someone strip flock two others I bought at the same time and the fitter was critical of the flocking, but I understand that has not been an issue in others, and in my case, was corrected in two at the time, and I’ve had the new to me K2 strip flocked since it arrived as it was rock hard.
And I’m not sure that for any wool flocked saddle that was 20 years old that strip flocking wouldn’t be a good idea anyway. But as far as how they have held up – my SLK has been redyed, as the black had seriously faded, but structurally, it is in great shape. The K2 was not well cared for by its previous owner, but with good care and conditioning it is coming around. Structurally, other than needing the strip flock, it was in good shape.
I would not hesitate to purchase an older one, especially if it fits you and the horse, and you have a good fitter to check it out. Also, be aware that their different trees fit differently. For instance the K2 tree fits “wide” so a MW fits like a W, and the SLK runs narrow, so a ExW fits like a Wide. So, for instance, my boy is in a MW K2, and an EW SLK dressage, and they fit the same.
