I ran into this info just now that might help, or jostle memories.
was this a guyed crankup?
This page at K0RC's show the light weight T-354, which has the flat bars
like you say.
Was the H-354 a heavier version?
Apparently yes? listed here on page 5, you can see the H-354. (there was
also a THD-354, and a HS_354)
K0RC has other pages there with more info
picture of one from 1971 is here: (page 4)
