G15CS Braced handlebar

Another G15CS question. Thanks for past assistance. Attempting to determine original G15CS handlebar specifications. Seen several aftermarkets with 28 1/2" - 31 1/2" wide and 7" to 7 3/4" pullbacks. If you have original pair and could provide specifications it would be greatly appreciated. I only have old photos of my 67 and wasn't clever enough 50 years ago to measure.

Best Regards
