Some more info. Based on the colour and size of the TIG welds, the frame material appears to be aluminum. In 1995 Parkpre only offered two aluminum models, the AL-U-Max and the Pro Image. The frames appear to be identical except for the material. Normally, the better material would use a larger diameter seat post but in this case both used 27.0mm posts in 35.0mm seat tubes. The AL-U-Max used Alcoa 7005, while the Pro Image used Easton Pro Gram Elite. I don't suppose the tubing decal is still on the frame? Barring that, if you stripped it down to the bare frame and weighed it, we might be able to determine which one it is, as we have a known reference point from an old road test which states that the 1995 Pro Image frame weighed 3 lb 4 oz. for the 19" version.

I just had another thought. I wonder if the extra 'A' in the serial number simply designates an aluminum frame?
