seat binder addendum(b):

[at the risk of ]

in looking through the famous Bozzi catalogue of 1950 discovered that a binder of this pattern is illustrated on page 20 of the document

it is assigned the internal Bozzi item number of 1537.

in the listing is a W.A. done in boldface type

this is the Bozzi designation for an item produced by Way-Assauto

mentioned earlier in the thread that have seen the binder on Allegro products at least as early as 1937 but do not know a launch date for the part nor its employment by Allegro. Allegro appears to have fitted it to their cycles at least up through the mid-1960's. Way-Assauto began in 1906.

of course it is possible that more than one firm produced binders of this pattern...
