Was there ever a European-made camera (thus not rebranded japanese) that got an FP-connector/setting?
Non comes to my mind.
"F" connector/setting is something different from "FP".
My sources say to use the M setting for FP bulbs.
Brian though explained that FB bulbs fire faster, thus the synchronisation should be a fit faster (shorter delay than M).
This is where the bulb manufacturer’s data sheet is important. For example, select “FP shutter” at Thomas link:"What is the Guide Number that should be used for calculation of exposure aperture?"

Older Kodak Master Photoguide has a flash calculator that can provide GN if data sheets not available.I have some Sylvania P25B available for sale, mounted on the original cardboard holder, and there is no visible Guide Number data, as the original external packaging is missing. No suggestion of P25B available on the Phillips link either. I have found data sheets on the web, but no Guide Number suggestion...what Guide Number?!
[edit] I finally found a GN datasheet for P25B: for ASA 25, GN = 80 when 1/50 shutter speed. Other shutter speeds have other GN. So ISO 100 has GN160 at 1/50 shutter speed.
The we have the issue of date of chart for Guide Number, and the fact that ASA values were re-rated (about 1960 IIRC), so then changing what is found in a pre-1960 chart to suit today's ratings.
Indeed. But if the chart said "Plus X", did that assume the ASA 64 rating or the ASA 125 rating? If the chart was ASA rather that film type, you are correct about the rerating simply causing you to look at different column for film speed.The re-rating of DIN and ASA film sensitivity only referred to the films.
Are you selling some?With the size thing I in first instance referred to electronic flashes and their manuals.
But if you got a sketch of a bulb and only a plain guide number it helps too.
I already referred to it, but again. In the 70's the reference film speed incorporated into a guide number changed typically from 18 DIN to 21 DIN. Thus another stepping stone to have in mind when only having got a guide number.
Yes, I got a lot, but no "Texas" ones as indicated.
Isn’t FP synch a 15ms peak “delay” versus M synch’s 20ms peak “delay”?
Bulb data sheets are also useful sources...
The only old, german engineering textbook I found that covers this FP matter states that manufacturers of focal-plane shutters, due to manufacturers of flash-lamps typically not spreading output curves for FP-lamps, to offer only one synch-setting for all types of flash-lamps, of 16-18msec pre-run.Thus I can't be blamed for not using it. Or for hinting at M-sync, when that is what shows up at a lamp manufacturer's catalogs for the FP version.
