Bicycle Mechanics - Saddle Help

This isn't necessarily a mechanical problem, but it seemed like this was the only viable section to post this sort of question. If I am wrong, I appologize.

So basically I bought an old Centurion Le Mans touring bike a little bit back and it came with (pictured below) saddle, I am not sure if it is stock or custom. I am currently building another bike and would like to try and get another just like it, or similar, the only problem is, is that I cannot tell what kind of saddle it is.

Looking at the bottom it says:

Kashima Saddle MFG Co. LTD
Osaka Japan
5678 9012

I tried looking up Kashima Saddle Co and I cannot seem to find any information on it. Would anyone by chance know kind of saddle this is by sight, or happen to know any comparable brands?

It is much appreciated.

It's an uber-cheap and fairly uncomfortable saddle that was common on cheap bikes back in the 80's. Tended to lose those nuts that hold the rails to the shell. Kashima is still around, but they're based in Taiwan now, I think. They don't make anything like that anymore though.
Why you want one? Like the waffle pattern?

If it's the waffle pattern you like, find an old Schwinn saddle. They are probably wider than what you have, though.

i may have one off of an 80's murray. the vinyl seems to be in ok shape, but the bike was outside in the rain so long that it was completely froze up. if you want it, i'll try and get pics. shipping costs will make it yours.

Yeah, it is definitely nothing special and it isn't the most comfortable thing in the world, but I've been riding with it for a while now that I find it comfortable, and enjoy using it. I moved it over to the other bike I am building and it looks pretty good on it at the moment, so out of familiarity as well as aesthetics, I'd like to find another one.

Torchy: I'll have to start checking out old Schwinn's, thanks for the tip!

Jco1385: If you have pictures, I'd be glad to see them! I am in San Francisco, any idea on how much shipping might be? Not that 5 or 10 bucks would matter, just curious.

i can get pics up on monday (going out of town this weekend). should fit flat-rate USPS for cheap enough. might even have 2. if so, i'll squeeze them in the same box.

That would be excellent, and much appreciated. Thanks, I look forward to hearing from you after the weekend. Enjoy your trip?
