I'm sorry to hear about your husband. I'm sure he will be missed by many.
As for the Lewmar 7, I asked my wife to trim the jib to starboard. Pop! My Lewmar 7 landed in my lap on the port side rear of the cockpit! I ended up buying one on Ebay for $20 plus shipping. Normally, they go for about $80. There is also a Marlon winch for $67 new from Hamilton Marine or a #6 winch for $97. Both light duty but probably fine to replace a 7.
