You would be best to contact Hamilton directly through the "Contact Us" feature on their webpage with respect to your question on whether or not the stainless steel bracelet would work on the H70455533 / H70455733 and visa versa with the leather strap on the H70455133.
The reason I would not commit to the interchange of the 38mm Khaki Field bracelet between the stainless steel model and the two leather strap models is based on the case redesign on some of the 2018 and 2019 models, as discussed in the thread below.
Your best option is to send Hamilton an email as I outlined in my above post, and they will forward your question to a local Swatch Group Service Center in your area. The advantage to this is that if they provide you a bracelet based on providing you with the wrong information, I would think the onus will be on them to compensate you for their error.
