Default Knock Off Locks

I was at a collector car dealer recently and noticed the wheel locks in the photo below on a SuperPerformance GT40 replica. Were these type locks every used on Cobras? They look like the would be handy to use but possibly prone to theft.

I believe these Halibrand "safety pins" were period correct for the Shelby Cobras of the 1960's. But rarely used on the Cobras in competition. GT40's maybe.

Bob at Vintage Wheels can supply these and I have them. I wasn't aware though that they dated back to the original cars.

It appears they have them installed backwards. The coil should be in the hub. Doubt it would last very long flailing around the way it's currently installed. "Sure it's fun until someone loses an eye..."

That coil might be a bit long to fit inside, plus harder to squeeze if they did fit.
Don't think they'd last long as shown in the picture. I'll take safety wire instead.

Knock-off locks and or even safety wire were not used in period, especially the competition models.
A word of caution safety wire will not keep the wheel from coming off if the knock-off comes loose.

CompClassics is absolutely right. Safety wire might save your knockoff (spinner) before it goes flying off if you notice the slack change in the safety wire soon enough , but it won't save a wheel. Hopefully a driver would notice wheel wobble first and pull over and stop.

The pin type might give a little extra cushion/time to pull over before a wheel comes off.

He's also right that they were not used on the period Cobras. Comp or street.

Safety wires were a more recent thing required by some competition sanctioning bodies.

The safety wire (0.41" not flimsy 0.32") will save you from losing a wheel by not allowing the spinner to start loosening during braking. Not a hard job as the spinner does not have much mass. It's not like the spinner can stretch the wire.
As far as leaving the safety loose to see if the spinner is moving is a real head shaker. I've seen that comment before on the forums and wondered why an improper safety (read that loose) and expect it to do its job? Sorta like closing the barn door after the horses get out.

I'd also trust the safety wire more the the C-clips as all photos I've seen on the installation the clip's shaft is not right up against the Spinner face, which could allow the spinner to loosen 1-2 revolutions before the clip stops it.

Sorry to soap box, I've never been let down by safety wire in the last 39 years in aviation.
