Thanks for the response, I like the way the one in the pic was mounted with internal fixation rather than the usual external brackets

I do fear that it may now have to wait a little while however because after almost 7 years with the same company I was called in on Monday morning and told that my position had become redundant effective immediately

so on Monday night I re-did my resume and the next morning started pounding the pavement , so to speak . Oh well ,on wards and upwards.
