Question about Erla cowling for late Me 109

[RolandF]

"Red 7" D-FWME is a re-built from a Spanish Buchon brought up to the standards of a G-4. The engine is a DB 605 A, so I´m sure this one is no reference.

The "G-4" does have not a standard 605 A oil cooler housing. The shape of it are much more in line with the Erla G-10 model than MTT. My supposition, and that's all it is, being that the restorers/converters wanted to use a Fo 987 and still have more of a G-4 look than a MTT housing would provide.

That's my story, anyway.

Best Regards,

Hi D.B.

"Red 7" has the standard G6 (DB605A) cowling (it is not anywhere near the G-10 type). I think you are confusing the size of the oil cooler intake, which is in fact, of the larger type. However, the entire cowling cover is not G-10. What makes a G-10 cowling are the larger chin bulges, which were added to accept the larger coolant lines for the DB605D...it is not the size of the oil cooler intake.

There is nothing on Red 7 that makes the cowling a G-10 type.

When the K-4 had the chin bulges missing, it was because the entire cowling was made larger and streamlined (as opposed to manually adding chin bulges), to compensate for the coolant lines. The difference is so minor, it is not noticeable in photos.

Mike, please note "oil cooler housing" in my post.

I guess that in this paragraph, "K-4" should be read as G-10...

There was only one chance that the K-4 was "chin-less", and this occurred with those very few produced by Erla (W.Nr. 570xxx batch), which retained the same external characteristics of the G-10s produced by that firm.

And, IMHO, the lack of the chin bulges is very noticeable on photographs.
