Because that's an early Schwitzer bar type as opposed to the more common Eaton spring.
These are usually more costly for that reason alone,not to mention the condition,distinct applications and date code his is showing.
I am not at all up on the current market value of these,but if I needed one I would highly recommend continually emailing the seller repeatedly with an offer of $1000.00 or more in hopes that he would eventually end the auction early.
