K31 scope mount questions

[TargetTerror]

I know this has come up before, but the current crop of scope mounts seems to be from different manufacturers. I don't see the "St. Marie" scope mounts anywhere - have these become the "Swiss Products" brand scope mounts?

I want a detachable scope mount for my K31, so I've narrowed the choice down to the following:

http://www.brownells.com/aspx/ns/store/productdetail.aspx?p=1666 (aluminum mount)
http://www.aimsurplus.com/acatalog/Schmidt_Rubin_K31_Scope_Mount.html
http://www.brownells.com/aspx/NS/store/ProductDetail.aspx?p=25696&title=SCHMIDT-RUBIN%20K31%20SCOPE%20BASE

Anyone have any experience with the Ranch Products mount from Brownells? The price seems right, and it is the only one to take standard weaver-style scope rings. Also, is the scope mount from aimsurplus the same as the Swiss Products model from Brownells?

Thanks!

I saw those items at Grafs, and that is precisely my question. Everything is either "Swiss Products" or says "see Swiss Products" - none are specifically by "St Marie". I'm I correct that this is the same manufacturer, and they just changed their name?

We are one in the same. When Mr.St.Marie and his partner became a LLC they gradually changed the name to the last part, Swiss Products for simplification.
