I just have the one gen I 8” but you’re welcome to use the pictures I posted or I can take more if needed

Great work mhayashi thanks so much!

Sounds nice! I should have posted an update but I had the same experience, that the lack of rubberizer led quickly to new cracks. I did however have durable (>1 year) success with flexseal. I applied...

I have an RD Gray extreme angle periscope around somewhere that covers 8x10 at 115 degrees ~105mm. I don’t have any scanned examples but there are some on google, not a bad lens.

Oh and also VM says New York branch was opened in 1902; since it has NY and Leicester/London engraved then maybe 1902-1907 ¯\_(ツ)_/¯

Very cool MH! Thanks for solving that puzzle :) at least my initial “project it on the wall” test looked like an image circle at medium distance bigger than 4x5 at f4.5
Yeah ST this won’t be as...

I'm sorry for the terrible quality pictures! I'll attach better. Yes it's engraved for 3 1/4 x 4 1/4 with 8" equiv focus, as in the attached ad from 1904 (taken from Colucci's site)

What do you think, around 1900ish?

Thanks Dugan and malexand!

Ok thanks everyone! Your answers gave me the confidence that I was looking at a stuck insert so I got busy with the vice grip and hammer. Booyah-defeated!! Fits nicely now. Looking back at the...

Thanks kindly Dugan! Do they both have name plates for 4.5 max aperture?

Thanks. It just seems strange cause the rear cell fits just fine. I usually use a sinar copal but the rear cell come back too far for mounting. 213071

213070Hi all,
Recently I separately obtained a Radar 12” barrel with an iris diaphragm, and a broken betax 5. After getting the shutter going again, I was looking forward to mounting the Radar, as...

I used klean strip laquer thinner although I assume any strong nonpolar solvent might work. MSDS says it’s about 1/3 each methanol, acetone, and misc alkanes. Once it evaporated the rubber was not...

Oof sorry. I don’t forum much but I should have known better :). Is there a way to change it now?

Wanted to share a new thing I tried. Hope it’s not heresy or old news but I stumbled on this while trying to do the acrylic resurfacing technique but wasn’t sure how to soak the curtain in paint...

The beseler c6 has a great rangefinder with multiple built in cams (90, 135, 250) and a focal plane shutter to boot. https://lommen9.home.xs4all.nl/American/beseler%201.html
