My '74 had a straight alloy post with steel clamp so no country of origin on that but OEM was a Brooks Pro saddle and Nitto stem, and not the TA Cyclotouriste crankset (3-pin instead).
Yeah the cyclotourist crank makes it a bit hard to date as the '73 and earlier bikes came I think with stronglight cranks. Still parts got switched around a lot during the boom years. I believe the early moto GRs had a 531 DB main triangle and fork and became full 531 DB around '77. The 531 stickers are toast on my bike so I can't read the main triangle sticker.
