I did this too. Once you get through to someone there, they will re-register you using the contributor case number you want. It was very quick, probably 10 minutes total including hold time.
I am looking at a Mannlicher 1888/90 here, wouldn’t this not be considered an antique rifle and not pursuant to the FID requirements? I am in the process of having my FID finished, but I kinda want this thing now. Fires 8x50 fixed ammo, but it’s not commercially available, and it is pre-1898. Unless I’m mistaken, that qualifies it as an antique, right?

And how does this system work? How do they determine a large, paved area and what is not? There are many different areas that are not even possible to measure properly.
