It's a great shooting bow, I had one in the late 80#s.

 

There seems to be more info on the take down styles but not the 1 piece recurve. I believe the 1 piece bow is considered a Magnum 1?
for $50..Gonna be adding this one to my collection.:wink:

 

The Mag 1 is a one piece but that doesn't look like a Mag 1 to me. It should say Mag 1 and Dynastressed for the limb construction. Yours looks like a lower end target bow but it's still a steal for $50. I grew up near Harold Groves shop and bought a used Spitfire for my first real bow 36 years ago.
