Can you supply a Findenser with a B29 joint at both ends? It is not possible to manufacture a Findenser with a B29 socket in addition to a B29 cone, as B29 would be too big for the outer metal fins section to fit over onto the glass body. If you need a B29 joint at both ends, order: RR31102: Findenser B29 Cone, B24 Socket – 400 mm long plus RR139142: Enlarging Adapter Ordinary B24 to B29 (to fit in at the top, to enlarge the B24 socket to B29).
