Solved.

Look like Dale's. Don't know model numbers.

Like these Vishay/Dale's: Digi-Key - BC27KW-2TR-ND (Manufacturer - PR02000203272FR500)

Philips SFR25 or nowadays VishayBCC SFR25 5% metal film.

Hi
The Last two bands look like brown and red in the piccy. If that is correct .

Brown = +- 1% Red = 50ppm . Im Guessing you already know that.

Thanks for all of the help. Yup, the last two bands are brown and red on all of the resistors. They are 1% and 50ppm. I suppose this rules out the Vishay BC Components SFR25, as they are all 100-250ppm, even though visually they look very similar. Also, the SFR25s are marked with only either 4, or 5 band color identification, whereas the mystery resistors are all 6 band.

Any other ideas, or suggestions?

I think I've found them. Thanks to Jeronimo2003 for pointing me in the right direction. I believe they are Philips MRS25. Here is a picture from an eBay seller, they look identical and have identical specs:

I am sure they are of german origin, but I can't remember the exact manufacturer.

hello.
this could be a (vishay) beyschlag res, mbb0207 (1%, 0.6w,50ppm).
here is a picture of a new one with rohs conformity.

Hi

Out of intrest what are these resistors installed in.

Im guessing with the simple exterior of resistors lots will look exactly the same.

I found them! They are Philips MRS25 and are now made by Vishay. They look and spec identical. Thanks to Jeronimo2003 for pointing me in the right direction. Here's a picture of some for sale on eBay:

The dark green ones are indeed from Philips, I have thousands of them, but the white are not Philips.

For the longest I've been trying to identify these resistors. I would like to find out the brand and model number if possible. Any help would be greatly appreciated.

They are metal film, light blue in color, and have a 6 band color identification. They are approximately 7mm X 2.5mm.

The closest that I've found are the old Roedersteins Resista MK3 resistors.

Here are some pictures:

The pictures are from a Goldmund product made in the 1980s.
The resistors are made by Roederstein. They were made in light blue coating and blue coating. I don't remember the difference. They are no longer in production.

The company I work for (OEM for industrial electronics) uses these lightblue MRS25 resistors by the bucket load. Most of them 1%, where necessary 0.1%. I'll look up the manufacturer tomorrow and report back soon. I wouldn't be surprised if these are indeed from Vishay, as you already mentioned.

Yup, Vishay.
