Kilgallb, pictures of the boxes are in the first post, no connectors on top.
Take care, if you have the Beseler Dichro45 head the box are similars to the Universal 45 system but it is not the same and it will not fit.
The LFPF member who bought the 35mm box write to me that he received the box but that it didn't fit his enlarger. He probably have the Dichro45.
The Universal 45 head is that one, pictured below.
The 35mm box is now in California, the member want to sent me it back and sent the check too (make no sense for me!).
My suggestion is instead of sending it back to Montreal and ship it again from Montreal later, if someone in the USA wish to have the 35mm box, it can be sent directly from California.
I still have the 45 box, I listed it now on eBay (I'm Durstfanatic), so you can take it there, exact package size and weight is entered so it should be near the 12$ by Small Packet Air as I said earlier. The 2 boxes cannot be send together from Canada by Small Packets.
If theses boxes interested you, please let me know that I arrange shipment with the first buyer.
