Help Identifying this gun

[X27]

I know it says Benjamin marauder but it is nothing like I have ever seen before. 
Any one know what this is?

Its a custom made receiver that replaces the benjamin receiver. I could only find one company making that style and they didnt have any marauder receivers left only 1377, 22xx and disco ones.

It is a Russian made Dobermann pistol ​made in very small numbers by a hobbiest, the various markings you see are to get around the ridiculous Russian laws.
