I agree - most red tips I've seen for sale are without case. I was quite lucky to stumble across this little beauty a month or so ago (and got it for a really good price too!):
Both razor and case are in good condition - unfortunately (for you Kev), it's not for trade - as much as I like and want your Hoffritz!
But, they are out there and don't have to cost too much either - I managed to pick this one up for about £15! Including shipping from the US, it came in at around £20. Keep looking on ebay, they do crop up occasionally.
