Nishiki decals source?
Not long ago (8/1/2024 to be exact) I posted a question regarding an early-70s frame, stating that I would be using to build a mid- to low-end Japanese tourer with spare parts, largely to see if I could do it for close to 0$ and because I didn't have a vintage Japanese bike in my collection since I sold the Miyata 1000 some time ago.
As I was finishing the "spare parts" bike (photos of which will be posted when I get the requisite number of posts, btw) my next-door neighbor offers me his son's bike for free - he just needs to clean out the shed. We go into his shed and it turns out to be a 1981 Nishiki International in quite good shape, having been hung inverted from hook through the rims. Yes, it needs some work (e.g. the bars were wrapped with electrical tape way back when) but it is complete and rust-free.
So here's my question: Is there a source for the "NISHIKI" decals/stickers on the down tube, the "INTERNATIONAL" on the top tube, and the "N" logo (the kind with the multi-color semi-circular ribbons around the "N") on the head tube?
The font for the brand and model are an all caps Helvetica-like bold italic font in light yellow. (The bike frame is blue).
I would really like to bring this bike back to like-new condition and the decals are missing letters and showing quite a bit of wear.
Thanks in advance.
