The Brevex firm in Suresnes was led by former Radom engineer Mr. Polonsky and remained active from 1948 to 1959.
They manufactured two types of actions on Mauser factory machinery obtained after the factory was dismantled by the Allies in 1946, the M300 for the .375 H&H Magnum rimless length cartridge and the M400 for.416 Rigby and .505 Gibbs, obviously adaptable to other munitions, including .460 Wby.
These true magnum length actions were used by many gun-makers and among them Rigby's for building large-bore rifles.
They were imported to the United States by Tradewinds of Tacoma,WA.
However, at the beginning of the sixties, Marcel Pigatti resumed the production and produced a few samples of these very sought after big bore actions. Some changes have been done like a lower bolt handle, simplified firing pin while the receiver was no more of the C type.
These actions are machined from drop-forged blanks and were well heat treated and Rockwell hardness tested.
Here is a sample bearing serial number 8 and SRP marking (Société de Rectification Pigatti).
It has been entrusted to us by a customer who wants we use it to build him a .505 GIBBS…nice work to come !

Regards to all.
