I just grabbed these old vintage Grover bridges off of ebay. But if you look at the pics most of the slots look really weird. Deep and V-shaped. Is this how Grover bridges were, back in the day? Or did I just buy some leftover bridges that somebody has already modified and left for dead? I was hesitant, didn't bid a lot, but somehow "won" the auction anyway.

Note: This is what I always tell my wife. "I didn't think that bid would hold up!"

I would assume they are cut for nylon strings?

Up until fairly recently nylon strings were thin (and historically gut or silk), much thinner than the polyester "nylgut" strings sold today which can be nearly twice as thick as what was used prior to the 1990s/early 2000s..

I think these have been messed with by someone.

The two in the back look unmolested with much smaller slots.

Try them out and see how they sound. If they sound OK, I don't think it matters much what they look like.

Looked at these as well. You could always sell the wide-slot bridges for those looking for nylon string bridges and make your money back and then some.

Slots can be filled with cyanoacrylate glue and ebony/charcoal dust. Sand smooth then recut the slots.

measure a slot

how deep does a string go in the slot

Just to the top of each string, so logically, they would all be different depths.

If they aren't, then still test how they play, those are good 5/8'

Ain't nothing wrong with those bridge slots.  They are cut with a triangular file, not a rectangular nut file like the last two in the box.

Mr. Stelling cut a lot of bridges that way (not all), and I have a bunch of them.  Also, the notches are rounded a bit from front to back.  This allows the string to vibrate without the chance of dampening by the side walls.

I've found Mr. Geoff's bridges with slots like these to have a strong and clear sound.  Suits his banjos.

Try them out, see what you think.

Alex Z I concur and it looks like maybe the same file was used for the Stelling nut

They have arrived. I haven't had a chance to try one yet, but folks might be interested in the weight and thickness of vintage, pre-china, Grover bridges.

Average weight - 1.62g
Hi - 1.83g, Low 1.42g
Width at the top, just a hair over 1/16", as compared to around 1/8" for many modern day boutique bridges ( most of which are solidly over 2.0g in weight).

These bridges play just fine. With the deep slots the action is just a tad lower, which is fine unless you are already in danger. I'm not noticing any problem with strings being at uneven height, but maybe my picking is not precise enough to notice!
