J hoag adj powder chg bars

[SWANEE]

Can anyone put a date of mfg on these adjustable chg bars, also was this HOAG gent a California gun smith? Any help would be appreaciated. I also have a tool head drilled out for 7/8-14 dies, it only has a number marked where star would have their name and pat #.  I know it is not a berdon cause I have several of them, did phelps have a tool head for standard dies ?
