[Ratsnake]

I recently obtained a real nice Erfurt Double Date, Police Rework. Pictures posted, it has the "police safety sear" fantastic grips, matching mag. However, it appears that all of the "straw" parts ( I haven't checked the mag release) have a different number as the rest of the gun. The serial number is 1010, and the straw parts are marked 05, the rest of course 10. I would like some comments and any information you all might be able to provide me, Thanks,
Ratsnake also, no police unit makings on front of grip strap.
