I'm afraid I did not have a very good experience with Comerfords in the early sixties. They advertised a 350 Goldie in MCN, I made a phone call on the Saturday morning, salesman said it was still available. Travelled all the way from Norfolk on my 175 Mondial, thought I had gone to the other side of the world.
When I arrived I was told it had been sold, no apology just said have a look and see if there is something else you are interested in, my reply being NO I want a 350 Goldie.
The next week it was advertised in MCN again, my brother gave them a call, and they said they "still" had it in stock, when ask why they would not sell it to me last week , the salesman said he would check. Then said it had been sold. I personally don't think it ever existed, just a ploy to draw you in.
