I don’t think the first commercial 45’s ever used a 78 sized groove. Be hard to get 5 minutes of music on one side of a 45 using the wider 78 groove. The whole 45 system with changer was ready before WW2 and was held up because of WW2. Do you know of any examples of 45’s with a regular small center hole? [9/32”?]

Subject: Re: [nevec] Rare records need to be digitized.
My reccolection is that the first 45's had a standard LP hole until the 'stacker' was invented for automated players. Thats why all record players of the 60's on up came with the 'Puck' to fit over an LP spindle for the revised 45. I don't know if the first 45's used a 78 needle but it is possible, until the BiRadial Saphire or Diamond needles were born.
Hope other NEVECer's have other thoughts.
I have many 78's and LP's. Cannot find my collection of 45's, probably lost in one of 5 moves!
If anyone interested I have about 12, 7" reel tapes used by TWA for music entertainment on their aircraft. Have to wait for better weather to get them out of my shed. Last time i played one on my 7" deck, about 5 years ago the quality was excellent.

I have these 5 one-of-a-kind records from my 80-odd year old friend with some folk music she made with other people in the mid-50's, probably in Greenwich Village NYC. She asked me to help rip them to digital, some kind of archiving project she is involved in to save these recordings.
I ultrasonically cleaned them last night, that appeared to go OK. 2 of them are the same, 12" 33-1/3, with aluminum discs inside the vinyl (one has a slight chip). These play somewhat OK on my turntable although it sounds like there is still a bunch of dirt in the grooves.
The other 3 are all different, 7" discs, either 45 or 78, I can't quite tell. The turntable I am using only does 45 and 33. They have a 9/32 hole, not a 45 hole. (were there any 45's that had a small hole? this would be a hint).
With the LP stylus on my turntable, the sound is almost inaudible and the tracking of the needle makes a noticeable stripe in reflected light on the record surface. AGGGGAAAHH, needle-less(!) to say, I stopped immediately. Is it possible that these may just need a 78-sized stylus? I do have a couple of turntables that do 78, but they will need some TLC (a miracord and an older garrard, iirc). While I am up for trying that, I would be interested if anyone know someone that specializes in such efforts. I'm glad to pay for the help, should the 78 turntable resurrection doesn't work out. I may try the audio place in Harvard square (if they are still around).
