I'd opine the bullet tip w/guiding eye which is the particular variant in this pass around would be the closest match to the featherweight.I just started working Monday so now I can afford to ship package to the next person on the list.
Also as a side note is there any of the full size that are as mild as say the featherweight razor. My brother loves the brass micromatic but said it's a little too aggressive for him. He said the featherweight aggressiveness is great. I want to find a full size brass one that is mild like the featherweight so I can get for his bday.
The only micromatic that might be closer to a featherweight or G - bar is the 1949 - 1950 micromatic bullet tip which isn't in this pass around. They changed the razor head 2 to 3 times between 1947 and 1950. The first versions had the guiding eye made from 1947 - 1948 then you had ones without the guiding eye from 1948 - 1950. They changed the razor heads for sure in 1949 and possibly in 1948 when they dropped the guiding eye from the razor cap. If you wanted one that for sure was made after 1949 you need to seek out the micromatic bullet tip with the plastic tto knob on it.
