This Seth Thomas ship's bell movement seems to have a non original regulator which won't show in the dial regulation window and has only one wire to touch the balance spring. Please share any ideas on how to remedy this problem including replacing the platform or regulator.

Does the clock run and keep time as it is now? Once regulated it should not not require frequent adjustment. Replacing the escapement is usually costly. I believe that you can reposition the pointer to point to the scale.

Not familiar with that movement but is that a non-original platform escapement?

I can't recall ever seeing one with a platform. Usually just a balance wheel setup.

Here's a Seth Thomas 115-D. Not sure what the differences are between the 115-C and 115-D. I have some smaller fuzzy images of a 115-C and at first blush they look pretty much identical - both have this type of platform balance. FYI they can be a little tricky to get the 1/2 hour odd bell setup.

So that is a 115-D and the platform is very different from the one in the OP's 115-B. The questions is, is the platform a replacement in the OP's clock or is it an earlier iteration. It looks like a replacement doesn't it?

Here's a picture of the two side by side. Looks like the OP's has a 4-point mounting and the other a 3-point mount along with other differences. Don't know what is original and what is not but it would be interesting to see whether the OP's movement plat has the hole for a 3-point mounting underneath what's there now.
