Why do you need the images scanned on a drum scanner. Do you simply need high quality and high res scans?
There are labs around using Professional Quality scanners that are not drum scanners, such as the Kodak and Flextight
I did a quick Google search for "film scanning service" and got lots of hits, You could try Colab in Coventry

Drum scanning is exactly what it says. A trannie ( or neg) is placed inside a clear perspex tube. The tube rotates. Inside the tube a point light source scans the trannie, like a needle playing a record.. The light passes through the perspex to a detector head , light is converted into digital data. The drum spins fairly fast and the scan takes place slowly, building up a high resolution image.
Drum scanners were orriginaly developed for the printing trade outputing the data as CMYK files. Several were adapted for the photographic industry, and output the information as RGB files. Drum scanners in their heyday were very very expensive and required a lot on care to keep the drums spotless.
The advent of digital photography has seen there use diminish, however some are still in use. So called flatbed scanners are now popular, due to their lower ( much lower) cost.
and their ability to produce quality scans without the hassle
Use this link if you want to see what a modern drum scanner looks like.

In the early 90's i worked for a company called Optikos, it was a pro lab that offered a complete photographic solution, from comps to slide copying, i used to do all the E6-C41 processing, we had a machine installed called a 'Kodak Premier' and that was a drumscanner come digital retoucher.. like Photoshop, but before it existed.. i think!! lol..
Anyway, it was an amazing bit of kit.. the drum was quite big, it took at least upto 10" x 8" tranies.. we done the Vodka adverts, the ones with the picure of the bottle with say, bee's flying towards it and the reflection thru the bottle was helicoptor gun ships.. remember??
The drum if i remember rightly was filled with oil.. the whole thing was over £1,000,000!!!
THAT was an expensive drum!!! lol..
History lecture over.. we can now resume normal programming..
