Thanks for comments and criticisms.
Dewbakuk- the original model was a AMT/ERTL DS9 Runabout 'Rio Grande'. I think the scale was 1/72, but it is plenty big enough. Still find them on Ebay. There is a great example in the future wars thread 'the game that never was'
Alien surfer- I see what you mean, I would like to say it,s just the camera angle but it looks even wierder with the cargo bay removed.
first pic with a few 28/30mms for scale

next pic from the rear (aft?) with the tau hatch mounted upside down, I think.

next is the soon to be magnetized separate cargo bay. possibly the reason this project got shelved for a couple of years.

and last a pic of the ship upside down so you can see the underneath so far.

A bit more glue and paint and its almost there........
