WTB AEG / Lomo bottle capsules (M1, M3, M5)

[Text_Edifice]

On the very unlikely chance anyone has one of these - I picked up a bottle mic with an M7 and M15 cap and I am really interested in tracking down one of the capsules made by aeg / rtt in the 90s that fit the oktava and rtt preamps.

Really I'm just being completist - I doubt I'll need both the M7 and the M15 and I think the lomo head has a different sound again that might be useful.

Anyway, if you have a line on one of these I'd love to hear about it.

Cheers

Dave
