THE CHC COLLECTION

The CHC layout has dramatically changed since our move to a smaller area in 2013/14. What you see pre-dates that move. As we launch this new website we are in  a state of flux but open for business as usual. Nevertheless, although not all we own is or can be shown in a photo album, it gives one a good idea of the size and scope  of the collection
The vast majority of our exhibits are not powered-up, but were they to be so, they could be demonstrated in full working order. These are just a few of our exhibits.
