Best 61B model padlocks

[Riyame]

Thanks everyone for the info! I'm strictly interested in Best locks from a collector standpoint--I've collected them for decades, but have little documentation about them. Based on the catalog info posted, I have at least 4 examples of the 61B722 padlock. I wish I had an example of the 27B or 37B. It's a shame they don't produce the wide variety of specialty locks they once did before Best Lock changed to Best Access.

.

There was 1B, 2B, 4B, 5B, 6B, 71B, 14B, 8B, 81B, 91B, 21JB, 4M, 27B, 37B

The 21JB is a normal padlock body with a cable instead of a shackle, the 4M is a cable lock that looks like a bicycle lock with a long oval lock cylinder housing.

1-6 are normal style padlocks. The 5B is fairly rare and was only produced for a few years.

71B, 81B, 91B are all high security padlocks with the protected core faces.

8B is a bigger brass padlock. 14B is like the 8B but half the size. I have only ever seen 2 of them before, quite rare and never seen them in a catalog.

27 and 37B are bigger padlocks steel bodies, 27 is normal while the 37 is shrouded. They do not have the core protection.

Many thanks for the details. Many of these I've never heard of or seen before.

As an aside, it appears that one of the locks I have that I thought was a 61b is actually a 6b, at least according to the paper wrapper it came in. From what I can tell, the 61b is the same as a later model 6b, with the exception of the loose throw member. Every 2, 4, & 6b I have seen has the fixed throw pins which are part of the lock.
