|Summary:||SMC whitelabel produced carabiner for A5 (and signed by John Middendorf)|
|Description & Commentary:|
This is a basic oval produced by SMC for A5 Adventures, big wall climber & gear designer John Middendorf's climbing equipment company.
The design has a protruding nose, a definite step forward in oval carabiner design, but common since the 1970's when it was first developed. A few benefits of this feature:
This example was generously donated to the collection by John - his signature is clearly visible, even if slightly worn in transit from Australia to California. In correspondance with John, he shared that the carabiners "cost $2 each in 1987 with a quantity of 5000."
The the markings are fairly detailed - a clear logo, serifed font with clear changes in stroke width. Interestingly, the 1990 A5 catalog (#3) lists strength as both 4000lbs and 2000kg.
