Loewen window balances
We may be able to supply these balances, yes, but I'm afraid the stamps alone don't tell me what you have. That only indicates weight, it doesn't have anything to do with the overall configuration. At this stage you could have anything.
In order to narrow it down further, I'll need you to remove these balances and show me a clear photo of the top and bottom ends, as well as whatever attachments are connected at those points. We especially need to see the attachment at the end of the cord.
From there, I will do my best to identify a good match for you.
Thank you for these photos. These are a step in the right direction, but unfortunately we're still missing some important components. As mentioned above it's very important that we see the clip or shoe at the end of the cord. Yours appears to have broken off, so you need to use an undamaged balance as reference.
This is a very important detail and we can't proceed without it. Please let me know if you're able to get that for me.
That does put us on the right track, but this part is unfortunately too damaged for me to properly identify. Might you have one that's still in undamaged condition?
