0 BarryG Posted July 23, 2004 Share Posted July 23, 2004 More than likely 50:1. I've got an 87 and thats what it is! Link to comment Share on other sites More sharing options...
0 New Yankee Posted July 24, 2004 Share Posted July 24, 2004 yep - 50:1 since 1964 or so (I THINK '64 but you're unquestionably safe there now!).From failing memory, the late 50's and EARLY 60's used 32:1 for the most part - some of the earlier vintages 24 or 16:1.
