WEIN Razor Ebay Vintage Question?

[Zorro]

Hello all,

I would like to ask if anyone has an opinion on this razor? I was trolling Ebay for some vintage razors and caught this one for a very, very reasonable price. It is in excellent condition. No nicks, scratches, dents, chips, etc. Clean throughout, closes evenly, no rust, so on. It measures 4/8 and it might be shave ready. It passes my forearm hair test. Will give it a shave tonight.

Oh, its a 520 WIEN and I believe a silver steel model. (See attachments)

I scanned the web for some links describing this razor but no luck. Maybe someone can render a view.

Thanks in advance,
John
