What kind of frame ? Please help

Hi there. I'm Tom and I come from Polish.
I turn to you, kindly request the identification of my new frame.
I bought it at auction portal in Poland. A similar theme is found in the retro forum in Poland, but unfortunately I did not even identify. Only we all say that the frame is probably derived from the years 1991-1998. He asked me for help in identifying this frame because I wanted to build a bike similar features as the factory if it is an old frame. The only information that I know about her is that the seatpost diameter is 26.8 mm size of about 20 inches and the frame serial number stamped on the seat tube. If necessary I can give you a serial number if it will help in identifying the framework
I would also like to apologize for my not so good English language


Reports the serial number : D079168P

Serial number might help, so post it up. Blank out the last part if you want and a picture of the rear mech hanger / dropout might help.

EDIT I see that picture in your links. So not a replacable dropout.

Looks like a repaint finish. Would guess not a high end frame. Aluminium frame and I don't know tell tale marks on these.

Looks like the welds might have been filed down or enlarged..
