IIRC correctly somebody on ebay was selling rebuild kits for the Indestro pear heads. It's been awhile, and can't remember the price, but might be worth a look/see.
The lever is no removable, but it probably wouldn't be too hard to rebuild it if I had a kit so I'll take a look.
There's some sentimental value to the ratchet, but I also just plain like it.
Low tooth count and a larger head, but it feels good in my hand and the head isn't too fat.
I like them, too. As fas as pearhead ratchets go it's neck-and-neck for my fav (along with the vintage Herbrands).
Could be either a Batman pawl or a Nighthawk pawl. You could always found a donor ratchet and swap guts. They're relatively easy to find and cheap, and yours has sentimental value.
Mine has the batwing pawl.
Maybe I will eventually find a donor ratchet.
