Some of the early A-1 handsets had a mouth-shield on the handset microphone. http://www.beatriceco.com/bti/porticus/bell/images/we_a1_phone/front.jpg If you hacksaw that off (after all, it's only a telephone, right?), then it should fit. The model 500 style works fine, and is what it was designed for. So does the model 700 style ("Princess"). The "Celebrity", with its fake retro handset does fine.. http://www.beatriceco.com/bti/porticus/bell/images/dl/celebt-a.jpg But, the celebrity phone is a little hard on the goam lining the lid. The later, squared off handsets will sorta work (if your foam is in good condition, and you aren't trying to use the modem in a very noisy place.) They might deform the cups. The extreme scarcity of telephones with handsets is probably the reason why this hasn't gotten the level of offers that it should :-)

is the B model still in the wooden case? Steve On 8/30/2013 12:12 PM, Fred Cisin wrote:

The illunination of the rotary dial Trimline is a very simple circuit. There's a bulb in the handest, just abovve the dial, using the dial 'number palte' as a light guide. An extra contact o nthe hookswitch (i nthe base)) conencts it to the outside pair (black and yellow) of the noraml telephone cabel. And you feed these from a little AC transformer. My Trimline was misisng the bulb when I got it. I found somebody on E-bay seleling electriclaly suitable bulbs that were a littler too long mechncailly. So I gut them down. Seriously. Well, I fut the end off the pastic wedge base so they would go in the socket a bit further. So far I've not made up the transformer unit. There is no point in me getting one of the US ones (I think OldPhoneWorks list them, they certainly have some Trimline parts, like the line and handset cords [1]) as that would be for 115V mains. It's just a transformer, soi it's bot beyodn me to make one, I'm just out of Circular Tuits... [1] The origianl Trimline line cord connecotr had 5 contacts. the 2 sides of the telephopne line, the ringer return wire (so it could be connected to local groudn for party lien ringing) and the 2 wires for the lamp supply. Most of them used on standard lines were rewired internally (on the screw terminal plate in the base)so that only 4 of the cotnacts were used. The OldPhone Works cord only has 4 contacts. Since I whatned to keep my Trimline as origianl, I bought 2 of the OldPhoneWorks cords, borrowed a cotnact from one to make the other oen a 5-contact plug and wired it so that the rigner return wire was conencted ot the approrpatie side of the line. ROFL!!! I found an Ericofon in a London 'junk shop' earlier in the year. Not working, so it was priced low enouch for me to just afford it. After cleaning the contacts and stripping/cleaning/lubricating the dial and hookswithc plunger, it works dine. It was fitted wit ha 6 contact Australian plug. Yes, I kept that. I bought a few of the sockets from a company in Australia, and wired some of them to connect it for a normal 2-wire telephone line, a british Plug 431A (with the rign capactir on tie master socket, and even for GPO Plan 4 Multiple (the old type of plug-in telephone over here). Soem of them are very interesting. The Planset, for example, a telephne that can link to 2 extensions and communicate with them and with the exchange line. There is no external relay set, the swtiching is in a plinth unter the normal Telephoen 706/746. The same plinth was later used to house a 300 baud modem known as a Modem 13. The 13A is originate-only and uses a lot of port core inductors, op-amps and signle TTL IC (a 7403 used as an XOR gate IIRC). The 13B, which I have not investigated yet (yes, there's one here) seems to be originate/answer and uses moe complex ICs (I think there's a couple of PLLs in there, for example). I think the Telephone 741 with this mdoem plinth looks a lot nicer than the Bell Dataphones I've seen pictured on the wrb... The TRIMphone is IMHO a design classic, of course. TRIM = Tone Ringing Illumniated Model. The ringer is a transitor oscillator, nto a bell. the 'warble' is still very well known. The rotary models of the TRIMphone had illumianted dials. Unlike the US TRIMline, they didn't have mains trnsformer. Nor did they draw current -tony
