My colleague got this from his Grandfather.  Measures 49" nock to nock, and has the number 3451 stamped on the right side of the riser.
Any info would be appreciated.

And...gee....I hope these pics show up.
If not, small laminated riser, green glass on front of limbs and dark maple colored glass on the inside of the limbs.

 
 
 

No pics!

Measure from nock to nock following the curves of the limbs. I'll bet it's a 54'' bow. If so it may be a Hunterflite. We need pics to verify.

Finally!  Success on the pics!

It's an early "Hunter-flite" model--probably from the late 50s.
