BSA Condenser, contact breaker
A contact breaker condenser, part number 19-1747, used to suppress arcing at the ignition points.
This is a condenser for the contact breaker, part number 19-1747. Condensers like this one work alongside the contact breaker points to suppress arcing as the points open and close, which helps the points last and keeps the ignition spark consistent. It shows up in the electrical equipment sections of the parts books, filed right alongside the points and the rest of the ignition components.

Our records show it appearing across a few catalog listings from 1969 into 1970, but the entries don't tie it to a specific model or engine family, so we can't say for certain which bike it was originally fitted to. If you're matching this up to a points-and-condenser ignition system, bring in your old part or check the wiring layout with us before you order.
The manufacturer tag on this one says BSA, but condensers of this type were common parts across British marques of the era, so don't read too much into that alone. Give us a call if you want help confirming fitment.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
