It does have some taped layers but I suspect this has more to do with the stick winding than for insulation properties. Without an occasional layer of tape, the winding would fall off the side. I guess these were hand wound using a pretty crude method not dissimilar to how we would do it today as hobbyists, just a rotating 'stick' and some guide rails and plenty of 'glue' in this case.
