Bass/Lead head?

[BuddyDog]

Found a listing in the local classifieds for a Rickenbacker Bass/Lead amplifier head with an Ampeg V4 cabinet.

Any idea what a Rickenbacker Bass/Lead amp head is? Seller is asking $200.

Could be this a B410.

Or this a Transonic 200 head.

Wouldn't recommend either for bass, though.

Could be this a B410.

Must be a converted 410 as I miss 4 10 inch speakers. here you can find the b series amps catalog scanned to have a look at the pictures and see if it is a B series amp.
