For your consideration...here is my '73.
Some observations:
1) The fuel vent looks to be in the exact location except mine is a touch further away from the rub rail.
2) The rubrail appears to be one-piece aluminum, just as mine was.
3) If that is not a V20 logo, somebody should have sued.
4) Logo on the rear, just behind the whitewater when zoomed I can see a tinge of what looks to be appears to be the the red/white/blue "W" logo just aft of a word strikingly similar to the word "Wellcraft"
5) Everything else about the photo points to sub-1977 V20
If I had to bet on it I would say V20...even though there are slight differences. The world may never know!
