Hi 5ash,
I guess we are talking about the common skywatcher 50mm finder that comes as standard with lots of scopes.
I replaced mine with this seal from 'RENSEAL":
52 x 1.5 N70
43 Amberley Cres. Dandenong. VIC 3175
(03) 9794 5711
as pictured. Contact details are in the image.
If you have any issues I have spares and can send you one.
Cheers,
Danny
