M39 male threads needed

I love to adapt older lenses but these days I have MFT and Sony E, so I make adaptors for M39 thread. They fit either system and will go on my Leica too. At one time you could get an adaptor that stepped down from M42 to M39 for a couple of pounds but the supply has dried up. There were until recently a plethora of the same adaptors with 0.75mm pitch thread rather than 1mm which I need. I suspect someone made a batch of the wrong uns.

Any suggestions?

I've tried body caps and discovered that they are not for me. Its hard cutting a round hole in the middle without specialist equipment.

Extension tubes are another possibility, but can be expensive.

I have found the odd enlarging lens adaptor cheap, but there aren't many about.

A picture of one of your adapted lenses would help. I have better luck buying adapters for M-Mount and converting.

This is a 39mm male thread-


Extension tube sets are available on Ebay for $20 or so.

Thats exactly what I want but it's pricey and I'd like 4 or 5. The old adapters were going for £2-£4 this will be about £13 each. Now why don't these show up when I search?

Re the M mount: Good idea, but it won't get them to work on my LTM cameras. However I'll look into it.
