What is this? (on facebook) (Edit: identified as MBK)

Presumably repainted as a 'dale, unusual rear drop out, internal clamp seat post? Seat cluster looks a bit Saracen but cannot see any road bikes in their catalogues of the correct era.
looks like it might have some chainstay rust under the paint.

Seat cluster reminds me of a GT

The seat cluster does look similar to some of the aero road bikes from GT, for example the '97 and '99 Fury but I cannot find any round tubed steel frames in the catalogues that don't have the more pronounced triple triangle. Might have missed one though.

Looks good value though.

Thanks! Spent too long last night trying to figure it out. Looks like probably the Trainer model. Seat post bolt recessed in back of top tube rather than a quill seat post. Topic title updated.
