Default fibreglass masts

We have an 1965 Laurinkoster 32 MkI in our yard with an unusual mast. The mast appears to be fibreglass. It's of an oval cross-section, with a beautiful long taper above the single spreaders to the masthead. In a few areas of print-through (and in one tiny gelcoat chip), a very fine 'glass weave is visible. When knocked on, it returns a dull, solid sound; no metallic ring to be discerned. The rig is slackened, and the chocks are out; shaking the mast at shoulder-height above deck reveals it to be a bit of a noodle.
The spreaders and tangs mount to a stainless sleeve of some sort. The mast step is also stainless, and adjustable. There is no sign of corrosion or failure anywhere, excepting that one tiny chip and the inevitable gelcoat powdering. There are no internal halyard runs.
As far as i know, the Laurins didn't come with these masts, but then again, many of these early models were built on a semi-custom basis, so anything is possible. Has anyone heard of a fibreglass mast of such vintage, or on such a scale? Is it possible that it's some kind of composite construction, perhaps 'glass of light metal? Everything i find online in this area is regarding dinghy and sailboard masts.
