It's definitely an Aerospace Sport model, 1975 or 1976.
I have two of these. Your fork is original, but not your shifters.
Your bottom bracket bearings are pressed in. I have ridden mine thousands of miles and the huge bearings are still perfect.
Very good geometry on these. Just like my classic Holdsworth Special!
Mine are the same color, btw. Blue cloth tape was standard.
I don't like the shifting of those old Shimano derailers. Hard to shift one gear at a time on the smaller sprockets, even after lubing everything and really fine tuning. I did find out that those derailers will perfectly index a 5 or 6-speed freewheel using a Suntour 7-speed shifter!
"BTW, you might find the shifting improves a bit if you slide the rear wheel forward (a little) in the rear dropouts."
