Hi, I have a SF DR that has "A 41015" stamped on the chassis. Does anybody know what year it is. All I found was a chart in the net that didn't cover this specific number.

1974

Here is a link to the chart that shows it:

Wow, that's a lot info. So according to this source, my DR should be from late 1974.
Thanx bunches for this link.
