That is an odd shoe! Could I see it from a few more angles? I'd like to see it from the side. Can you also confirm if there is a wheel inside the shoe? I can't quite make out if there is or not. Thanks!

Here are additional pictures. Yes - there a 2 sets of dual plastic wheels.

Ah, I recognize this balance. Unfortunately, that shoe has been discontinued and is no longer made. I believe the depth is 1-3/32". Can you confirm? If so, I recommend our S385-15 channel balance with a 1420 stamp option. This may be able to work as a substitute.
