CCS made amazingly well padded protective cases for cameras.

See http://www.ccscentre.co.uk/product_ranges/classic/slr_pouches.html
for details of products - I think this is the Tusker Large but can't guarantee this as I have had it some time. I do have the shop ticket for a Tusker Large but I have had other CCS cases so not 100% sure.

Anyway, internal length: approx 21cm. Zoom length (i.e the extension under the camera body: approx 14cm.
Massive velcro closure, internal drawstring and belt loop.

Very good condition. Internal pocket slightly abraded.

Feel free to get in touch if you want to inspect the case or make me a good offer.
I can post at cost price of postage.
