I bought a 3 element trap yagi antenna that was disassembled. I was told
it was a Hy-Gain model. After laying out the parts I can see that it
doesn't look like a Hy-Gain model because of the following:

1. It uses large diameter, single traps. These are identified with color
coded lables (red, green and blue - radiator, director, etc.)

This is exactly like my old Mosley TA33Jr. Not at all like the HyGain TH3.
Ditto for #2. On my TH33Jr, the elements were mounted via aluminum blocks
with little U bolts. If it is Mosley, the length of the boom will be a
giveaway as to which model. I would try to download some manuals from the
Mosley web site; it might be mosleyelec.com.

2. It doesn't have a "beta-match" - rather, it looks like the driven
element is directly connected to the coax. The mounting of the driven
element is almost exactly like the Hy-Gain style with insulators that
are mounted into a clamp that surrounds the boom.

3. The director and reflector use boom mounts that are different than
Hy-Gains. The mounts are made from aluminum extrusion and use a circular
opening to mount to the boom and have a wide, flat top that the element
bolts to.

Does anyone know what make and model this 3 element beam is? After I
'ID' it I can then get the assembly instructions so I know what
dimensions to set up since all of the joints on the elements are
"sliding joints" with clamps,

Thanks for the help,
