Thanks for the porridge joke - the old ones are always the best!
Forgot to say that the L/H tenor guitar had a pickup installed with tone & vlume controls on the left segment of the lower bout. The pick-guard was also set up for L/H playing - not much use to a R/H player unless there was a R/H Jimi Hendrix type who had always wanted an electric Martin tenor guitar!

The shop was called Biggars IIRC.
