If you are looking to sell or trade it let me know!

I have a distributor catalog c.1956 that shows Master Lock “Little Giant” padlocks as their nos. 44, 55, 66 and 77. The no. 3, as well as nos. 1, 2, 4, 5, 6, 7 & 8 were called “Secret Service” at that time. No. 22 was “Strong Boy” and no. 1500 was “Champ”. By 1965 the nos. 1, 2, 3, 4, 5, 6, 7 & 8 were still designated “Secret Service” while nos. 44, 55, 66 & 77 were then named “Wrought Steel”.
