1912 Erfurt Luger

[apachedawg]

I am new to Lugers and this forum and thought I'd show off a recent purchase. I found this at my local gun shop. The finish is very good, looks original with some light flecking on the barrel, some wear on the high spot on the trigger plate and the thumb disk on the take down lever is missing. It has a 3 digit Serial Number, X61 (X is a number). All the external parts are numbered 61 though the mag doen't match and appears to be from WW2 (Waffenmark with a 37). The markings are sharp. The grips show a little wear on the right side and are very dark. The barrel is mirror bright with sharp lands and grooves. It picked it up for $585 OTD. There are proof marks all over it that look like stylized letters with a crown over them. The forward mark on the right side is what looks like an eagle but not the usual Wiemer Eagle. It is also on the barrel shank.

Now a couple of questions, did I do OK? I think so. What is this eagle proof mark, Austrian? Should I replace or repair the take down lever even though it functions fine? What is a good way to clean the grips without damaging them?

Here are some pictures.
