[QUOTE="TimberPig, post: 1017527, member: 66421"] I thought they were steel until the late 80's? Or was it chrome until they switched to Nikasil in the late 80's? An easy way to check is to look at the bottom of the cylinder, the sleeve will be very dark grey next to the aluminum. The line will be readily evident. A magnet will also stick to a steel sleeve. Sorry if I was incorrect, not trying to steer you wrong, I was just under the impression they were steel sleeved back then. [/QUOTE]
