High Standard magazines

I recently acquired a High Standard Sport King SK-100, made in 1955. It was in such great shape for a 54 year old that I had to have it.

The big problem is that there was only one magazine. Does anyone know where I can get mags for this one? The current mags made in Houston have a different angle on the floor plate, so they would protrude below the grip at an angle, if they even fit at all.

Also, there is a little bit of creep in the trigger. Does anyone know of a site showing how to do a trigger job on one of these?

Thanks.
