Holster fit for OM Flat Top

I am trying to find a holster for my Old Model flat top .44 and am a little confused on what holsters it will fit in. Most holsters I see say they are for the new model Blackhawks or other Ruger SA such as Single Six or NM Vaquero.
Would a holster for the old model Vaquero fit my gun?

Any help on finding leather for this would be greatly appreciated.

I would talk with Rob at Simply Rugged: http://www.simplyrugged.com. He helped me when I was looking for a holster for Lipseys Flat Top which is on a smaller frame. He will be able to answer your question I'm sure.

Thanks I just took a look at Simply Rugged's website and most of his holsters are available for the OM Flat Top.
