I am about to re-cone (in a couple of weeks) a 6" PM speaker of near identical design of spider...

The spider is a bit unusual as it is also paper and similar construction in that there is a steel frame that is adjustable. That spider has fallen apart into crumbs.

BTW, your F.C. speaker also has a hum bucking coil.. A PM speaker does not have this so if you have not noticed hum it maybe O.K. Mounted in the baffle the hum may become more noticeable. Increasing the condenser MF after the choke will be beneficial in lowering the residual hum.

I would suggest re-cone that speaker as it is fully adjustable, even the field coil can be removed for repairs...

It is a learned skill but beware of shortcuts...
