this is just like a 1166 only with no gap,
wire is a bit bigger, this might have been a St Ives as the gauges are all the same, unlike the Carnhill 1166 which uses 3 different gauges,
wire is pulled very tight on these hand wound outputs, such that open windings from breakage is a very common problem, reducing leakage inductance is the reason for the high wire tension,
although the turns count is lower than the 1166, inductance will be greater as the core is laced 1 x 1 and therefore has no gap,
DCR was estimated on some of the sec winds as the xfmr came in for dissection with open windings,
if you have an original 2567, i can edit in the actual DCR if you measure it,
