Same as a Supro. Two coils like a P bass but the bobbins are made from Cardboard. Thescrew poles pass directly through that bridge plate. Very often they seize up.

Oright Spence,
do you have any specs like wire size , magnet ect. ?
thanks

Can't remember what wire guage but you could work it out. They meter at around 6 K so that's 3K per coil. I would think it's 42 AWG but may be 43 AWG. Look at the whole assembly. The plate on the top with the 6 holes allows adjustment of the poles. They have a slot-head and are essentially grub screws. Under the plate on either extremity are the magnets. ie., they are either side of the coils with the baseplate and top plate connecting the magnetic circuit like a keeper. They are a cast magnet, possibly alnico but I have no idea what grade. I've never had them tested but they do lose charge over time and can be re-charged with neodyniums.

Thank you for the help Spence.
I will get an airliner in the next days hope it works.
cheers
