The bus - the DM class of China Motor Bus (CMB) entered service in 1990 and 1991. It consists of 28 vehicles, all without air-conditioning. DM28 was the very last non air-conditioned bus to enter service with CMB in January 1991. It became part of the NWFB fleet on 1st September 1998 when CMB lost it's franchise. 

In 2000 DM9, DM12 and DM25 were sold to Citybus for use as driver training buses. The remainder of the class were withdrawn in 2002, and to commemorate the withdrawal of DM28 from NWFB's regular bus fleet, NWFB organised a farewell trip for this specially decorated bus, which took place on 17 August 2002 (Bye, Bye My Hot Dog).  It has, for some time, loyally served routes 91, 94 and 95.

DM28's 'farewell' livery features at least three tasty hot-dogs, which, in Hong Kong bus circles, is  jargon for non air-con buses. The withdrawal of DM28 also leads NWFB into a new era - having all routes being fully operated by air-conditioned buses.

First of all, the casting. The casting of the DM28 model is based on the casting of the KMB Dennis Dragon S3N303, as both of them are 'hotdogs'. For S3N303 the casting is okay, but for DM28, some areas need to be modified, to show out the differences between the both, such as the rear end. 
Some points should be noticed. First, the wheels. The DM-class used the wheel size like the KMB Dennis Dragon 12m 'hotdogs', ie. the diameter should be smaller. The class of S3N303, use wheels of a larger diameter. Thus the wheels on the DM28 model appears to be a bit oversize. Second, the rear end. The rear upper deck window still uses the small size of S3N303. The actual window should be as large as the ones on the upper deck sides. The top of the rear lower deck window should be level with the lower deck side windows, and not so squared as on the model. Thirdly, the air outlet wire gauze just behind the two 'hotdogs' on both sides. The real buses of both NWFB DMs and KMB
Dragon 'hotdogs' have these, except the class of S3N303. The DM28 model casting has not got these. Fourth, the doors of DM-class are not flush-fitted as the class of S3N303. 

Secondly, the paintwork. The advertisement is printed colourfully, in correct colours, and with 'delicious' hotdogs in accurate places. But some places are painted incorrectly. The large headlights are in the green of the advertisement, the rear lights have lost the reversing lights. For the route displays, the route numbers '94' are positioned in the middle of the side and rear displays. The DM-class used a three-track route number display, and the '94' should thus be biased.

Although the rear end of the model does not look like the real bus much, the quality of paintwork is high. I'll rate it at 7 out of 10.
