Some photos of the regular Tanaka (matte) and the Jupiter (shiny) finish. I thought I had a regular steel finish, which looks basically identical to the Jupiter, but I can’t locate it since I moved. Magnets basically adhere to the entire Jupiter finish, while for the matte version, magnets only stick to the cylinder, trigger and hammer. Btw, if anyone has one of rook’s webley cold casts, and is looking for a matte Tanaka m1917, let’s talk.
Was there no blue or violet tones in the Jupiter finish? Mine predates that IIRC, but has a definite Blue or violet cast.
