Thanks T-Mar, for this info and the Squint.

If a bike like this comes along really inexpensively in the right size I'd probably bag it as a spare but I just know I wouldn't use it much. I'm not a collector so no interest from that aspect. I'll go see it though when I get a chance to.

After breaking 3 frames at an average rate of 3-1/3 years each, a rear axle just last week and a barrel bolt rear rack braze-on a few weeks ago, it is wise to have spares!
