My updated list:

A linear SLI/H sodium lamp        Update 23/12/19 Finally found one of these 

A 10W and a 180W SOX lamp     Update 23/12/19 A 180W one is on its way

A pearl glass 80W or 125W mercury vapour lamp

A beehive neon lamp

A 3-way incandescent lamp (they never took off in the UK)

A 5ft 80W BC-cap fluorescent tube


And probably a few more, but that's all I can currently think of  

I have a g.e. 205 gumball

Mine would be a MA lamp and a 3BC MV lamp

Not much really

I think you mean B22d-3, there is a subtle difference between that and 3BC, which can catch out the unwary. There are usually plenty available on UK eBay, but if you get stuck I may be able to find a spare 80W one somewhere.

Best of luck with the MA lamps though, it took me 40+ years to find mine, and I only managed it with the help of another collector who pointed me in the direction of someone on eBay who had one listed under "filament lamps" for some obscure reason  

Sox35 - I've had a look and nothing comes up, probably should've expected that for a 1am eBay search . I don't think I'll be finding a MA lamp anytime but one can dream though.

Found these three. Two are saying they don't post outside of the UK but I have bought from two of the sellers here and I think they might if you ask.

I just want to get a truly clear F40T12 fluorescent tube.. Not the "cleared out" one.. The real one truly clear tgat whitesoldier86 has on youtube.

Maybe a t17 power groove would be nice too along with a soviet LTBCC tube with the color of 2700k.. The very rare soviet tube color.
Also a fully new GE BLB F40T12 with a NOS sleeve.
Also a modern Tungsram or hungarian GE F40T12 with color @5000k i dont know what color code it would be after 'F'
And the last one would be a soviet F58T8 fluorescent tube
 I know they existed but i never seen one

My bucket list is a 1920s Edison bulb

A beehive neon lamp

Well, we can scratch this off the list, Ria saw one on eBay, and I've given her the money to pay for it. 

Thanks, sweetheart 

Thanks also to Andy for telling us it was there 

My list is not too much, I've seen a local seller that still have brand new F40T10s, this kind of tube is rare for me, even more today in the T8 and T5 era. If anyone is curious here is the link of the product.
