I have come into a stash of these drivers. All are new and stock and are pre-arrestor spec — ie the same as you would buy today hut with no arrestors. I do not know of any CHBW that shipped with arrestor. These 2 model drivers largely differ only in the depth of the HF shelf… they fit into the same boxes.
Drivers are in the UK so there will be minimal shipping/postage costs.
email me for further information.

CHP-70.2
CHP-70.2 with natural/parchment or black cones. Gen.2 driver was designed with a shelved down response > 7KHz to provide a 'vintage tone' similar to some classic drivers. Warm sound with gentle emphasis in bass & lower treble to enhance clarity without excessive 'shout'; easy to listen to for long periods. Usual Mark Audio self-damping polymer frame, long-throw suspension and low-mass, shallow profile cone to improve dispersion. Suits wide range of boxes (miniOnkens, TLs, reflex, sealed, horn) and can be used as lightweight midbass with a tweeter and simple filter.
£40 pair = €45 pair + postage from the UK.

CHBW-70
CHBW-70 with black cone. A rare dedicated 4in midbass driver derived from the CHP-70.2 with slightly heavier duty coil, cone and suspension. An overlooked but very capable and flexible compact midbass. The response has a slight rise in the lower registers to provide a warm 'vintage tone' and weight similar to some classic drivers. Above 5KHz, output is shelved down, allowing easy blending to tweeters with a simple filter. Usual Mark Audio self-damping polymer frame, long-throw suspension and low-mass, shallow profile cone to improve dispersion. Parameters well-suited to a wide range of boxes (miniOnkens, TLs, reflex, sealed, horn).
£30 pair = €34 pair + postage from the UK.
