As of now there is no bid yet. The tag says Flui Dyne which is who took over Federal, so this may be a later model ski, or it may just have a newer tag. I do notice the two springs that keep the ski in position are missing in the photo, I would ask if they come with it. Flui Dyne should have them, or can give you the specs if they are not available. Paperwork is easy enough to come up with because its not serial number specific and applies to all 150's thru K model. All the flat spring gear legs.
I have an extra pair of 1500 mains for $500 if anyone wants to buy this nose ski and make a complete package. They include the brackets, but they will need new cables and bungee's, thats what I paid for them. They are in decent shape but would benefit from new poly bottoms as it still has the aluminum bottom and some wear. The STC called for 2000A mains which are the same length as 1500's with wider bottoms, the Federal ski owners manual page says either 1500 or 2000 mains are fine on a 150. Many folks have widened the bottoms and gotten a field approval as they then are the same as 2000's.
Good luck. If I didn't already have mine, I would buy this one.
