Old Brazil Mausers in 30-06: how strong are the chambers?

Have heard about these, and that some were supposedly built in the 1880s and converted to 30-06 in the 1940s or 1950s.

Already have read that original Spanish/Latin American Mausers (designed for pressures of the 7mm round) can be at the engineering design limits when converted to .308.

Have also read that some post WW2 Brazilian conversions to 30-06 were done with steel which was hard but brittle. Were all conversions to this caliber done after WW2, or were some done in the 30s or early 40s?
