This padlock had a high bid of $616.67 (Plus $9.99 Shipping).
Here we have a rare find! An early Clarke combination padlock. The only markings I see are on the back. 'Pat'd Feb.4, 1873, Reissued Feb.29, 1876'. These are Henry Clarke patents. Lock appears to be made of solid bronze. It is a 10-letter combination lock. I requires a 3 letter combination to open. It is in perfect working condition and I do have the combination for it.
The instructions to open the lock are as follows: You pull out the large ring in order to pull all the buttons in the OUT position. You then push the ring back in for easier access to the buttons. You then push IN the 3 buttons corresponding with the 3-letter combination. You then turn the ring to the right and the lock can then be opened.
This is an antique lock and it does have scratches and wear. Please look at pictures to see the condition. - eBay (12 Dec 2010)
