Welcome to the forum Dan. Looks like you have a 1st Gen G17 with a Born on date of February '89. Unfortunately it doesn't have any higher value with the <500 serial number. From other forums I have read, if you have a special edition or maybe a number in the single or double digits then there may be a few people that would pay more but the majority won't. SorryHello:
I have an early 17 with a serial number EU (<500) US. Does this pistol have any additional value over the newer Glock 17s?
PS. The information I looked up on the gun show it should have Austrian Markings.
