Very Rare Old Antique Iowa Lock & Manufacturing Co. Combination Lock
I recently purchased this fabulous old lock at an auction. It is marked IOWA LOCK & MFG. CO., BURLINGTON, IOWA, U. S. A., PATENTS PENDING. It has 10 brass push buttons that are very worn from age. I don't know what the combination is. It measures approx. 3 5/8" by 1 5/8" by 5/8". - eBay
Then the buyer figured out the combination, bringing a second auction:
rare antique combination lock. by iowa lock co. iowa usa. It took me three weeks to find combination. 4 digits have to be pressed. Its a beauty.

This lock had an opening bid of $1 and a 'Buy-it-Now' price of $200. It had a high bid of $91 (Plus $9.05 Shipping) but failed to meet the reserve price. I was listed again here with a 'Buy-it-Now' price of $160 but failed to sell. And listed again here for the same price.
