Arsenico, I applaud your work in interpreting for the members here. Thank You.

I have some old razor strops from Japan which arrived with covers over them. Much is written upon the strops and also the covers. Well worn, yet in wonderful condition, these strops are a pleasure to use. While 'Yamamoto' is written upon them in English and I suppose also in Kanji, Some more info upon them would prove interesting to me. I also have a razor which belonged to Yamamoto.
The seller told me they are vintage 1967 and 1966.
May I post pictures and request an interpretation?
Fine Regards,
Tom
