Well, as we have the "new Colletts from old", perhaps we could have this?

Uncle Lofty found his razor saw in the basement of his new dwelling,  along with three ancient Triang Clerestories (i dont even remember buying) and the remains of a more modern "vintage" one , (so old they had the original pin through the axles style).

Let the butchery commence....

V5, D15, C23 (2mm too narrow) but that may change.
