I have a 930. Bought it new in 1983. It's a workhorse machine. I can't tell you if the same feet will fit the 1130 tho. You can check with a local dealer for bobbins/feet/parts/etc. The Bernina USA site has a "dealer finder". You put in your address & it'll show you dealers in your area. If there are none close by then try another zip code further away.
