If this helps, my 73-750 had silver barrels originally, built 3 - 73 RH 5 head 32mm straight through. I painted them flat black ...thought it might help a little with cooling.

My 73 #107 is silver, will be black after the teardown to bore out & put a new cam in. My 71 750 was sliver too and got the black pimp treatment when it was down years ago.

You actually have a '74 "model year", so the '74 registration makes sense to me. The '73 "model year" had the RH4 head with 32 mm ports and silver barrels.

My '73 had black barrels, and I painted them black when I first re-assembled the bike. They've been silver for the past year or so, just like this:
