Mongoose Iboc

[mansion]

Hi can anyone give me the date of manufacture of my Iboc sport
Tange cromoly frame
cromo 4130 forks
Exage lx gears/crank
Exage country brakes
Araya wheels
Everything works fine but the gear levers are a bit of a mishmash

Cheers in advance

Judging from the decals I'd say it's a 1990 bike?? But I don't know that much about them. It's listed in here though:

(Man I'd love to have one of those IBOC Signature frames)
