Hans,
See I knew you'd be the best person to offer the explanation.
As far as I've been able to figure out the 105 was the boat tail and 115.x was used for all the Kamm tail and up spiders -- which I why I figured I could only claim associate membership in this lounge. wink
I knew that the 105 designation was used for a number of non-spider vehicles as well, and I could have guessed at two or three of them, but I doubt I could have come up with all five. As I've often said, my Alfa knowledge is limited to one Alfa and one Alfa alone.
Reuven,
You're welcomed for the message. I see you didn't need it. It's much better to have help from friends than to rely on any online service.
I've finally got some decent digitized shots of my car, but I haven't got around to posting them anywhere.

Until that happens, however there are a few pictures kicking around.
Ant posted one rainy day shot of my car in his piccies from Canada thread.
Ages ago I slapped up a few crappy quality shots on
Yahoo, but since that site doesn't permit remote linking, Hans hosted one of my old pictures on his site.
Basically it's just another red Kamm tail spider, with a few subtle cosmetic changes, but it's mine and I love it
