Fair price for unknown DWM?

[glock30]

This was my 1900 Commercial, it had a grip safety, 5 numbers, NO letters of course, it has been years since I had this gun, but this is it pictured with the exact same Mauser I just got back after 23 years, 10.2098. And Mr. Young, I realize that, i was asking the gentlemen for maybe he did not know? Being that people think a 5 serial number cannot have a grip safety, mine was 13,000+ and did. Thanks you Neil for actually saying it like that, i did not want to sound so stern, if perhaps he was making that mistake. By the way, this 1900 was all matching, but the breechblock had a different number? ANd it looked really good and exact, did people in the States fix them and maybe have provided this part?
