[QUESTION] Vintage Baseball Costume Sewing Machines Parts and Sales in Los Angeles

I've been hired to make some replacement costumes for a local baseball club who plays by 1800s rules and wears uniforms from this time period as well. There aren't any specific patterns and while I have found a few that might work online I was curious if anyone had experience with this. [Here] (http://www.whaleyhouse.com/vintage-base-ball.html) is the picture of their uniform, there is no zipper on them, and the waistband goes up in the back to a peak.  Any suggestions? 

Thanks!
