Westfalia Towbar cylinder barrel lock

could be you'll have to buy a new complete swan neck.

Thanks for that. Yes it does indeed seem I'll have to replace the whole tow hook. Seems daft that you can't buy a barrel lock separately, other makes seem to be readily available Witter for example. The Skoda lock cost me £15 and fits perfectly but the locking pin is too short. I'll have a think as to how this pin could be extended somehow and still be strong enough to hold against locking ballbearing. Please excuse my thinking "out loud". Tow hook still attaches ok but can't lock handwheel against theft obviously.

could you take the whole barrel to a lock smiths for assessment.

what about buying a used swan neck and using the barrel from that. just looked on ebay and found this.

Already tried locksmith and the lock is beyond repair. Also thought of a used tow hook and looked at some online. I'll go to local metal works and enquire about extending pin first.

Thanks again.
