UNKNOWN FILTER MANUFACTURER

Can anyone identify the manufacturer of this filter?

AgX · Oct 19, 2019

I assume it was made by Parra Mantois.

xya · Oct 19, 2019

it's Kinax, a french maker of cameras, enlargers and accessories. there is an enlarger on ebay https://www.ebay.fr/itm/183986217541

In French
http://www.collection-appareils.fr/x/html/historique.php?marque=Kinax
but apparently the PMP was associated with the enlargers and the meaning has been lost.

It's yellow,a bit on the greenish side. It its my IKOFLEX 2 would it be usable with black and white film?

AgX · Oct 19, 2019

I referred to Parra Mantois.
And you then come up with Kinax, however just based on a same abbreviation used at a complete different appliance.

AgX · Oct 19, 2019

In any case, that filter seems rare.

Parra-Mantois & Cie, a French company, which like Schott in Germany, Bausch & Lomb in the U.S. and G.B. Chance in the U.K., made scientific and specialty glass for astronomy, optical and photographic purposes.

Yes, that was the reason for me to assume them to be behind the filter.
But I wonder what the 2nd "P" stands for. Maybe a hue designation. But why then the punctuation?

xya, Kinax actually also made filters, but at least those of them I found on the net looked quite differently.

I guess the last word on that filter has not yet been spoken...

xya · Oct 20, 2019

if you look at the photos in the link I already mentioned https://www.ebay.fr/itm/183986217541 it is said what P.M.P. means. it is Précision Mécanique et Photographique, a society based at Montreuil. at least their enlarger was made by Kinax. and as Kinax made also filters, it could be the origin of this filter too. but that's not sure, they could have got it from another supplier and put their name on it. branding was quite common in those days already. anyway: at least we know what P.M.P. means...

AgX · Oct 20, 2019

That information was hidden in the manual,
https://i.ebayimg.com/images/g/8kwAAOSwrVRdpzNl/s-l1600.jpg

So we got a firm of the name PMP (La Precision Mecanique et Photographique) marketing an enlarger that was (toll-?) made by Kinax and thus offered as Kinax PMP enlarger.
That may explain the term P.M.P. on the filter better than I did. But what then I am missing is a filter-type designation on the filter. I would expect such on any filter other than a standard yellow one. Maybe this is a yellow gelatine filter and the dye has changed.

Problem is that on P.M.P. even less information I could find.than on PM ...

The filter appears to be glass. I am not clear on how gelatin filters are made. Is the gelatin sandwiched between two pieces of glass?

AgX · Oct 20, 2019

Gelatine filters are made by coating dyed gelatin on glass and then peeling it off. For more sturdiness the foils then may be sandwiched between two glass panes.
When knowing from the start that one wants to sandwhich the filter, one could coat it that way that it strongly adheres at the first pane already..

Is PMP glass considered on a par with SCHOTT and BAUSCH & LOMB?

AgX · Oct 21, 2019

The glass itsel may be from PM.
What PMP actuallly made is not clear. Maybe they just were a dealer. Or maybe they cut and polished the glass, made the rings.

There were two manufacturers of optical Glass in France. Both attended Photokina. But on Parra Mantois I have practally no information, and sad enough we do not have many Frenchmen or french knowledge here at Apug.

What do you mean by "on par"? The production quality/consistency or the range of sorts of glass?

anthonym3 · Oct 21, 2019

Yes overall quality./consistency,etc. You said it may be rare. Is there a known quantity of PMP filters? It's no doubt more well known in EUROPE than in the U.S.

AgX · Oct 21, 2019

First time I heard of that firm. I do not even remember ever having come across any french stuff, aside of one model Bakelite camera and Cokin filters and Gitzo stuff, at all here locally.

Long time the European markets were rather closed. It took to 1968 for the customs barriers to vanish between the few member states. And still then the foreign markets had to be entered. Exporting to West-Germany with already a long time established own photo industry would only have been possible by price or extraordinary features.

anthonym3 · Oct 21, 2019

AgX,there is an organization in PARIS,SOCIETE FRANCOISE PHOTOGRAPHIA that might be of assistance in identifying the filter. I have tried to E-MAIL them but could not upload a photo..Perhaps you can manage to do it. At age 79 I am not very computer literate

AgX · Oct 21, 2019

Just send them the Photrio-link to that photo or even better to this thread.

I tried to send it but perhaps it did not come through.I will try again.
