I recently acquired this Type 38, cheap. It's a Koishikawa with the serial number in the 1,976,000 range. It came with the dust cover and cleaning rod. The front band does not match. It appears to have given a Bubba inspired refinish job, reminiscent of the Magnese Phosphate on my German K98k. Is that what you all see? It's clearly not blued. Also the Mum seems odd. It looks "stretched" to me, although I can detect no signs that it was ground and re-engraved. What do I have? What is the approximate year of manufacture?
