Only the Pit Road photoetch set has what you need. But there is another option. The mast comes as four parts. You can carefully sand down the insides of each piece leaving only the latticework. You will need to supply the pillars at the corners. Then add the kit parts or thinner scratchbuilt details on it as appropriate. I did this and it looks pretty in-scale.

Forgive the half-paint - I had painted the lattice parts black to make it easier to see and all the gluing made it partially come off.
Excellent work there. I won't be trying that, it would go very badly!
