1983 Mongoose Pro Class

I have rebuilt this rare find mongoose (if you can help ID it awesome ) it was a rough bike when I got it but had a vision of what I wanted it to look like--It was given to me at my Brother in laws funeral so I rebuilt it as a tribute to him --he passed away at the young age of 54--It is a mongoose of sum description= no matchbox behind the BB and no holes drilled out on the rear brake mount ...
