Cattleya: Help with identifying and appraising!

[FSR2003]

I was hoping someone could help me identify my Cattleya Orchid and what one of these plants might be worth. I don't have any plans to sell them, but would be interesting to know what it's value might be. I've never seen this exact plant/flower in stores though over the years we have given away a few clumps of bulbs to friends and neighbors. Not to mention a few clumps have been stolen from our yard over the years. I don't know a lot about Orchids but I am pretty sure this is a Cattleya orchid. My mother brought one single bulb from Cuba about 40 or more years ago, it took more than 5 years for it to finally bloom and really start to grow. The flowers are approximately 6" or 7" diameter. It's growing off an old tree stump, well it was a live tree until recently but it was pruned back one too many times and is now a tree stump. Originally it use to bloom only in the winter months in south Florida, December/January. Now that it is so large, we see blooms as early as November and as late as March, sometimes in the Spring, summer and fall but not often. However, primarily and always blooms in the cooler winter months. With this large plant we probably get 20 to 30 flowers blooming per year. It blooms 1 or 2 flowers from each pseudo bulb. It has never bloomed more than 2 flowers from one bulb. They do not grow in sequence on the stem. If it blooms 2 flowers from one bulb, it branches off like a fork into two stems, one flower each. The flowers are very hardy, leathery texture, can easily last a month sometimes longer if left on the plant. It doesn't seem to completely fit into any of the descriptions of the suggestions made so far, something critical has diverged from the suggestions so far, usually the number of blooms from each pseudo-bulb. Blooms have a pleasant fragrance.
