Taipan 11.5x8...18 grams (narrow blade)
Brian,
Could you please post a couple of photos of this particular prop?
I have a whole package of unused, orange, GFN Taipan 11x7 props, those with blades that are pretty wide at their roots.
They are from about 24 years ago and wouldn't possibly fit into any normal spinner (except a back-plate-less Kavan).
They are also much heavier.
