The black krinkle paint heads ,which are more round, only use the short neck ones.
The long neck ones will not work in it. Last source I saw for short ones was at Bulbman.com a month ago. Look under Leica misspelled in some fashon.
What kind of !@# is that advise?
Its really wrong..
And you keep repeating it:
Photo Net discussion :
"211 and 213 bulbs fit only the latest models with the grey paint egg shapped heads."
Come'on where did you get that from? Surely NOT from the original documentation nor from praxis nor from...
"If you have a round one with black crinkle paint, you need the the short neck bulb coded VASEX or something close."
The VASEX is an early enlarger model from the 1930s and hardly the code-name for a bulb.
I actually have in my "collection" an original Leitz bulb marked even "Leitz" for the Focomat and its hardly much different (beyond the markings) than an Osram bulb of the same production period--- which differs hardly (for the most part in the materials used for the opalization) from those currently available.
What has evolved over the years in the Ic is the ability to take more powerfull bulbs. While the first series were limited to 75 watt bulbs the last took 150w (and in some press-room applications even 250w) bulbs.
Unless one needs to crank-out fast prints ("time is money") or really large ones I'd keep to the 75 watt bulb. They last the longest. The current crop of papers tend to be so fast and sensitive that for smallish prints anything more than the 75 watt bulb is too bright..

And an additional note. In addition to my few black crinkle Ic models I have a 1940 Focomat I / VUTOO with a tall (120cm), very thick (5 cm) column and 62×65 cm baseboard and it works fine with the bulbs one gets EVERYWHERE. It was, afterall, the source of that original Leitz pre-war bulb
I really think you are confusing the Focomat with the older Durst Laborators.. they need a special oversized bulb to get enough coverage..
