Louis, you are correct the rear sight was not exclusive to the Sequoia order.
Secondary question was every Sequoia fitted with this sight, as I have a recollection of seeing an image of one marked and numbered Sequoia example with the Tangent option??
The above rifle certainly might be considered just another "1925", except for the fore wood shape and the postion of the magazine
retaining ring...not tp mention the 1924 marking.
Would be interesting to know if your 9.3 High Velocity Model has the " Sequoia" forward set retainer, when next you have a chance to look.
How common are 1924 Models that were not part of the Sequoia order??
How did the " 1925"/" High Velocity" Model designation come about?...catalogue description??

Thank you Rothhammer for the sight and Model info.
