Well the stuff I paraphrased from my book is the only info I have on this event. It states that the 109s were all 'Gustav' variants. Now I could be wrong here but subsequent versions (K) were by no means sub-standard off the factory floor despite poor conditions and shortage. Just me thinking out loud as it were. It seems they ones the Swiss received were good enough to reverse engineer. As stated above they built their own that remained in service for quite some time.
