Missing old window balances

Question

Hi I am missing balances from an upstairs window which is about 33 x 30. The first two and the last photos are from a slightly smaller window downstairs. The second two photos are from the upstairs window for which I'm trying to replace the window balances.

The stamp on the downstairs window is 2630. The dimensions of that widow are about 27.5 x 30. Can you please let me know which balance I should buy?

Thank you.

We can help with this balance, yes. Can you just show me a clear photo of the top nylon fitting for the balance you still have? Can you also tell me the depth of that bottom nylon fitting you're showing us? Another way to think of the depth is the "heel to toe" measurement, pretending that it's a foot.

For the window with the missing balances, I'll also need to know the height of the visible glass and the exact weight of the sash. Please be as precise as possible.
