Found another Blitz saw, a BLITZ 502 Antivibration.
A bit dirty still but otherwise she's looking pretty promising.
Pics show her just after taking her out of the box she came in:

Picking up this 999f today.
These really are awesome saws that dont come up often.

Here she is, has a few battle scars but runs strong.
Can anyone tell me what stihl bars fit these, 066, 076, 084, 090?

 

[sawfun]

The Stihl 3002 pattern 14mm is the size bar mount that fits a 999, 076, 084, and 090, not 066.

Those 999's will pull like a Mac 125, though they weigh like one as well. They arevery smooth and easy on the operator.

Brought this BLITZ 504f with me from the International Oldtimer-Chainsaw Collector's GTG.
This one is a rebranded Oleo-Mac 252F.
Will need some TLC though...

Many of the vintage saws have such wonderful lines, that is one fine looking saw.

Italian designs with sleek lines, Stihl isn’t into that as much but the s-10 is actually a neat design in my opinion, but overall Stihl’s into over engineering stuff on occasion which tracks with the German roots of the company.

Hello,

I'm doing my Blitz 504f these days and found the piston being seized:


Both piston rings suffer from being dented as well. So I sought for replacement rings and therefor measured the piston diameter: 46 mm.
According to an IPL downloadable from emak (https://emak.ev-portal.com/Virtual_...essources/Motoseghe fuori produzione-1905.PDF) the B 504 is the same as Oleo-Mac 252 and according to Mike Acres site it ought to have a piston with 44 mm diameter rather than 46 mm.

But then again the emac-list doesn't mention type B 504F (f for frene = brake) but only types 504 and 504 AF. And according to Mike Acres site (https://www.acresinternet.com/cscc.nsf/GasbyManufacturer?OpenView&Start=1&Count=1000&Expand=101#101) there have been variants of both OM 251 and OM 252 with 46 mm bore and 53 cc displacement.
Is it possible my B 504F corresponds to OM 252S rather than OM 252?
The emak parts-lists isn't exhaustive regarding all different models but I haven't found any more useful information so far.
Does anybody out there knows more or has sources of further information?
