Help ID this spindle marking

[Ruxstel24]

A friend got this early front axle and is looking for any markings and found this on one of the spindles.
Looks like a P, K and F and the set of numbers.
I’m guessing a replacement from an aftermarket source.

Being's the spindles have the "flats" for Timken bearings, it would be later and could be aftermarket. Is the axle Ford ?

Steve, so far no other markings have been found. Neither the axle or other spindle.

A mixture of parts to be sure. Just how much of a mixture is not so sure. The key is in the spindle arms. The photo is not angled right for the left side, but the right side is clearly a later (raised offset) arm. I "think" the left may also be a later one. As Steve T points out, the flats on the spindles make them later also. The "drag link" is not a riveted or brazed type used before 1917, so it is likely later also. There would be some crossover time when the more common welded drag links may have been on over-the-axle wishbone front ends around '17 and '18. What we refer to as the "tie rod" appears to be early, up through 1917 or '18.
I am not familiar with those particular markings. They may be genuine Ford parts, or not. Ford started putting the "Ford" logo on those pieces around 1919 to protect against early day knock-offs. Although the timeline is short, there is a window of opportunity for genuine Ford parts to have not had the logo. IF The axle itself IS a Ford part, it really should have the "T-202" marking on each end, Whether you can find a maker's marking or not. If I recall correctly, the T-202 should be on the left end on the forward side, either way the axle is faced. I did once see a front axle that had the T-202 on only one side/end. Never did find a reason for that.
Early day knockoffs do exist. I have seen only a few over the years. Usually, the stampings are bulky, with rough edges and other tell-tale signs.
