I'll have to buy one of those first 😀

No, I'm sure I'll get that sorted. And I could always pop my Jupiter-8 on there should the situation require such.

still have some of those original Summitar filters laying around, but sold my 1940 Summitar. If interested in a filter just let me know. Some are with case.

My first Leica, '48 IIIc converted to IIIf BD:

It's all the Buzzardkid's fault 😎 The man made me graduate from Zorki to Leica so fast it would almost makes your eyes water...

Beautiful IIIc Derk. Looks like it has horizontally patterned sharkskin vulcanite. I understood that's rather rare. Sharkskin vulcanite is relatively common for IIIcs of this era, but most have it vertically patterned.
 
I found the articles Olaf Nattenberg wrote about the subject in VIDOM nrs. 98 & 101. It seems to be just that. Also, from the serial number allocation tables in that article, mine might actually be a IIc to IIIf conversion. Anyone here has the tables on that handy?

I might send mr. Nattenberg an e-mail, he seems to still be researching the subject.

Ron, I'll be PM-ing you about a filter at some point in the foreseeable future...

Calling the aid of Erik and Michael (seem to have misplaced the Bat-Lamp...😀):

Is the result of this conversion a IIc-syn, a IIIc-syn or a IIIf? I always get the numbers wrong on this kinda stuff...


Derk, gotta admit I'm enjoying the success of my 'come to the dark side' plot quite a bit and that the camera turns out to be a rare one, I find that really cool 😎
No better way to become engaged in Leica-fun, right? 🙂

Well, the research bit appeals to my profession and all the rest of it appeals to my love for both photography and fine mechanics. So yeah, you got me hook, line & sinker on this one 😀

Rick, I'll let you know but this one must've been done fairly recently - it feels almost new. So it might be some time 🙄 Though I still have to run a roll through it - you never can tell. Do contact me about that Zorki puzzle though!

This is a rather late IIIc converted to a IIIf, but the top-cover is replaced too.

The release-guard looks strange. It looks as if the diamond-patterned top of it is removed. Only a smooth tube is left. I never saw this before.
Michael is our release-guard specialist. Maybe he knows what's going on here.

Erik.
 
Erik, can you tell me how you came to this conclusion? I might as well learn something here 😎

So far, serial number and covering would match known IIc's with horizontal sharkskin: mine's 443798 and from the Nattenberg articles 443808 & 443860 are known to have this covering as well (www.leicapages.org under downloads; VIDOM nos. 98 & 101). This match is so neat it could hardly be coincidental but I have not actually seen those cameras nor am I a specialist, so you got me curious...

Normally, around the release-button of a IIIc-f-g a ring is installed, the top of wich is decorated with diamond-shaped knurling. The height of this ring is almost on level with the release button itself. On your camera only a short smooth ring is installed. I guess the missing part is about 3 mm thick.

Erik.
 
Oh, the guard! I knew about that. It's weird indeed, it would be fun if Michael had anything to say about it.

I was trying to find out what makes this a late IIIc to you and why you suspect the top has been replaced. This contradicts the info I found so far (see my previous post). That's not totally conclusive though so I thought I might ask & learn more on that subject, or get some pointers to find out more myself.

Derk
 
It is clear the top was replaced because the contactnumbers of the synch are engraved. Normally on a IIIc (or IIc) to IIIf conversion a little plate with the contactnumbers was mounted.

I was wrong, 44XXXX isn't that late. From 451001 the ball-bearings were installed. However, doubtless it received the ball-bearings during the conversion.

Erik,

I'd say that there is a later-fitted flash sync plate with numbers engraved on this camera, not a replacement top plate with flash sync numbers-engraved on it...

You are probably right! The picture, however good, is not exeptionally clear in this respect, but I take my conclusion back.

I do not have a IIIf myself, so I couldn't check.

Erik.
 
I see now! I'll post a clearer shot of the top. The light is gone & I don't want to go build a 'set-up' (ahem) right now, but I'll get those shots tomorrow.

I have to confess though that I've no further true data beyond the block of serial numbers in which this camera fits having been sent off between 1948 & 1951. It's just over a third way into its block of 9,999 numbers, so it might very well be a '49 instead of a '48...

I can't remember if I have shown this one before, but I have been using it recently and it really is a delight.
