Can you help to identify these frames, bikes or parts?

I've got what I think is a mid-80's gazelle Champion Monidal road bike that I'm about to do up as a fixed gear. Happy to provide pics but not sure how they did the track models over the road bikes.

Have a poke round on google, I have seen old Gazelles on various vintage sites and there's a site in Dutch thats explain the numbering systems for Gazelle frames which could narrow the date for you.

PM which elements of the decals you're interested in; happy to take requests.

Any chance you could give me a link to the frame number site? Cheers. Will start Googling again!

Edit: Found it but doesn't make any sense to the frame number I have... Hmmm...

Need photographic evidence of a similar model methinks.
