I got some Jensen P10R C5942 out of a Hammond organ. They are probably over 50 years old. I kind of slipped with them and my hand broke the paper awful easy I thought.
For someone who knows.
Do you think it would help to make the paper stronger to "dope" (I think is the term) up the perimeter, where most of the movement will take place, with some nail polish or fabric glue....i.e. before it breaks??

You can get them reconed. I think weber does that kind of work.

Think Cheap.

OK, here's the cheap: for tears in the cone or small punctures that you can straighten out the paper or smooth it back... use clear nail polish anywhere but the surround. You can also use a thinned mix of white (elmers*)For the surround use a self vulcanizing rubber product like a very thin coat of clear RTV silicone. I've heard some use rubber cement (but I havent tried it myself). My vote is with the RTV silicone. be careful with the amount and where you apply it. too much mass will lower the Fs (resonant frequency) and decrease efficiency. too much goop on the surround will have a similar effect. It's best to recone the speaker with a thin paper cone this will preserve the efficiency and the tone. you don't need Weber's magic paper, but it couldn't hurt either.

terry those are nice speakers. why you think that little organ sounded so good, id simply put them on ebay for 229 or more as is they will still sell. i sold a set one was smoth coned the guy had me ship one to cal. for recone, and one to him in vermount, theres guys out there wanting those speakers bad for there vintage amps and they got money, for what you could get for those you could buy a trany set for what ever amp you want. thats a great score for you take advantage of it mark
