Interesting stamping on HMV mainsprings

Post by barnettrp21122 »

I was cleaning mainsprings from an HMV motor, circa 1925, and noticed this stamping on the ends of both. Was this common on both HMV and Victor springs?

Also, the hardened grease was the worst I've ever encountered, even after soaking in solvent. I used a putty knife, wire brush on electric drill, and steel wool to hasten removal. It looked like steel filings coming off!

I thought that this is very interesting. I have no idea, but, does the dogs head look a bit odd / different ? Probably just me but it looks a bit like a ram or something ? :o

Here's a closer look at the stamping. Nipper almost looks more like a happy pig! :D
The whole impression is only a half-inch wide, so not much room for detail.

Hi Barnett,

I have rebuilt a 1907 or 1908 Victor III, a 1914 Victrola XIV, and a 1930 Victrola 2-65 portable. All these machines were totally original stock.

Both the Victor III and the XIV had the mainsprings stamped! The machines were 100% unmolested, just worn out and damaged. The springs were broken but the stampings were there.

I do not remember on the 2-65. The mainspring in it was in five pieces, count 'em, five, and I was too busy tossing spring chips out and marveling at its ruined state to bother. Should have paid attention but I was sixteen and stupid.

I hope we can get some more pictures of it! They're really neat and I think the Victor stamping on the springs is kind of a nifty little tradition from back in the day.

Bob,

I've overhauled several HMV machines of this vintage (HMV 511, 32, 163, 192 etc.), and yes, I noticed Nipper stamped on the end of the spring. Although I didn't recall that he was quite so rotund. :D And as you stated, the hardened grease was the worst I've encountered. It was petrified and I could only remove it by scraping with a blade. It was nearly impervious to the usual solvents.
Best regards ... AZ*

Interesting spring end! I recently cleaned a set of Garrard springs without looking for the stamping. I'll trust mine have them without going back to look! Thanks for the pic!
