I have also worked with paper tapes that seem to have been effected by acid in either the paper itself or the box it was in. In any event it was brittle and pretty tough to  transfer. Most of the paper tape, however, over the years.... was pretty good! There was one box that I saw in a collection that had reporters notes written on a yellow pad that was put in the box.There were clear indications of acid from that paper on both the box and the paper tape. As is the case with most tapes products - I suspect that some is good and some is....... wait for it.......

less good.

The Brush tapes benefited from the use of the NAB Stereo Cartridge head (3 tracks) because the centre track appeared about 100 mil, centred. Neither that nor the FT mono head were ideal, as the FT mono head had 150 mil of DC-erased noise and the NAB cart head was a bit less than half the track (43 mil).
