Recently I have acquired an Omega D2 enlarger and want to buy a glass plate carrier to be able to print my glass collodion negatives. The original no. is: 423-384
Here is a brand new one that seems to be available for a very low price. Look down to the middle of the page.
This shop appears to be going out of business, but slowly. That's sad. I originally purchased my Omega D5XL from them over 30 years ago. Still have the receipt. I'm taking a break right now from printing on that same enlarger.
I realize your location. I'd be willing to call them for you, if you like.
