I found two numbers on the head tube on either side of the Murray head badge. One reads MO65730 12, the other is B5253638.
This web page seems to indicate that an MO6 number indicates manufacture in 1965 - only it's in the wrong spot, according to said page.
I may, however, be able to find out more by emailing
these folks, but I should probably try to get better detail shots of the numbers themselves before sending them off. Mimi* doesn't have a chain guard, which is where Murray tended to put their model names, however, check out some of the wild "space age" bikes in this catalogue from
1963 . The cut-out crank and the seats are similar. 1965 may not be out of line.....
I don't know if I'm going to get out and play with her today though. I need to get a few things done around the house, particularly if I'm going down to Santa Cruz to meet Dad tomorrow evening, and then do the demo at the Santa Clara county fair on Saturday.
vittoriosa , if you see this and can recommend a restaurant or two, let me know (we've done Ristoranti Avanti and Omei, both good, but we're up for new things).
*Mimi is my cool aunt: the one who had a VW Beatle, then traded up to a bright yellow Kharmann Ghia cabriolet, of course. The one who went to work for an Indiana congressman (and his successors, including House Speaker Thomas Foley, who I met at her wedding). She who had the cool basement apartment on F Street SW with the exposed brick wall and the posters and the amazing record collection.
EDIT: In the nice surprise category. I just took a phone call from
baronalejandro - forgot I had given him my cell number when he was in town about a year ago. Did a quick garb consultation, then chatted bikes for a bit.
