It is Diamondback
I would like to know year, model etc.

I would look on bmxmuseum.com first then search the internet for diamond backs

That was first what I've done.
Thanks

I hooked a frame when fishing local river here in MN ,looked exactly like yours at first I thought "score" then I rembered how bumed I was when my PK ripper was stolen, so I donated it to my friends kid. I was told its a Haro race frame called a SR-71 or blackbird.
