What about a Bear 76er Recurve Custom Take Down Bow?
It's decribed as

The bow has a brown magnesium handle and white fiberglass limbs with black tips.
Most of the decals remain on the bow although some show wear.
The bow does have a sight pin.
The limbs show some discoloration/scratches and some rust stains at the point of insertion into the metal handle.
The tips appear to be in very good condition.
I would say the major issue would be the rust at the area of insertion for one of the limbs....one "bridge" shows some minor rusting while the other appears to be in very good condition.
Both of the holding "bridges" holding the limbs in appear to be very solid.
The bow does not have a string and I see no indication of the poundage for the bow.
This model of Bear bow appears to have come in four different draw weights (25/30; 30/35; 40/45; 45/50).

I don't know what "a pin" means in terms of archery.
Is there much difference in older technology, versus today's tech?

An older bow is more likely to be heavier than a modern bow. It is more important than you might think. Another important consideration with old fiberglass limbs is that they weaken over time and deform inconsistently. This isn't always true of course but can be.

Draw length isn't something that be be toyed with. Have your friend get measured. You can pick up some bad habits shooting bows that are undersized or over sized.
