Professor Marvel has linked to London Jack, I'll ad my 2 cents.
I contacted London Jack from that very website... a very personable fellow.
I ordered a Mauser holster and was told about 6 weeks delivery.
I received a fine product in exactly 6 weeks to the day, from England no less!
The quality of construction and pattern were first rate.
I highly recommend the gent as a maker and a man at his word.
