One of our readers send in the following photos and while I do not have a great deal of information to offer you about this particular chasuble, what I can tell you is that it comes from collection of Cathedral of Seville and dates from the first decade of the 18th century -- and as such, one can still see some of the influences of the 17th century present in the design.
In terms of its dimensions, it measures 136 x 132cm (53.5" x 52") and is, of course, violet with gold embroideries. It is quite a beautiful specimen from the period to say the least.
