Still off topic but anyone visiting they do a really nice breakfast in the Pudding Shop, The Square, Bakewell DE45 1BT (not the original I know Tim) with good WiFi so you can tune in to what's going on here, after you have finished it. Lovely lady who runs it too. Also there is a quaint old second-hand bookshop near to the river that is really good (think it funds the local bus transport for old folks)... I got a 400/4 service manual from there for £2 and they have some really interesting old books in there. If you park in the big car park just out of town (loads of space) then you can get £2 back if you spend £15 in the Co-Op. Just love Bakewell every time I stay at my bro-in-laws cottage.
Back to the cam ... I will get hold of my K4 cam over weekend and measure it as promised !
