I don't know what you can have shipped to SA, but I have always had flawless results from the RCBS two die set that I purchased decades ago and properly headstamped new brass is available from Quality Cartridge: https://www.qual-cart.com/375%20cal.htm

Here are some Redding dies listed (though presently 'unavailable') at a SA dealer's site, but at the equivalent price of nearly $350.00 USD (ZAR 5,250.00).

This set is identical to the ones I have used: https://www.gunauction.com/buy/8044051

A thread with some discussion regarding MS cleaning rods, as well as some lovely photos of member Louis' M1905: NitroExpress
I have seen them offered, and images of originals, in four or five piece sets. My M1910 TD Model has an original five piece set, each segment measuring 17.5cm.

Original 5 piece cleaning rod set, M1910

These rather nice reproduction four piece sets have been available for a couple of years via Gunbroker (U.S.): MS Rods

I've long been curious as to which MS were originally equipped with four piece rod sets and which with five. Perhaps I should start a thread to survey NE members and guests regarding their 'believed to be original' MS rod sets broken down by model, barrel length, proof date, four or five piece set, length of segments... . The 'likely original' five piece set with my 1922 proofed, 60 cm barreled, M1910 TD was in it when Grand Dad bought it at Ceylon in 1932. With all five of the 17.5 cm segments assembled it is 87.5 cm.
