Thank you very much Mr Gerst. I believe you didn't state any other identifiers is because there are none. My review of this site says serial numbers were destroyed. I did finally get the numbers from the seller, and he says the serial number is 40653 and the cone is marked WHF-55XX. Additionally, my review of this site found that WHF stands for Waldon Hi Fi, and this means a re cone? And value greatly reduced? Lastly, I have no clue what a surround is. Could you tell me specifically where and what I should be looking at? I've included a photo. Thanks so much again, Mack.
