Thanks guys. I was pretty sure it was a 7 The bottom left which has some of the edges of the design trimmed was my clue and now you both have confirmed my opinion. I frequently consult
www.theswedishtiger.com to ID these. The #7 there shows the exact same incomplete edges on the lower left side even though the site says a #7 "... is complete on both sides". BTW, that's a super nice #7 stallzer.
